Can't scroll with arrow keys in lightroom

I recently upgraded from Lightroom 3 to Lightroom 5 in creative cloud.  In Grid View, in Library, I always have an image selected and I can't seem to de-select it, so when I export a photo I also get a copy of the unwanted, yet selected image.
Also, I can no longer scroll through the images in a folder using the arrow keys.  Instead I just keep toggling back and forth with the unwanted selected image.
Seems like there should be a simple way to fix this

Try deleting the preferences: Preference and other file locations in Lightroom 5.  Note that on Mac, you'll then need to reboot your computer.l  Sprinkling this magic fairy dust fixes a surprising number of problems.

  • Bug? Can change swatches with arrow keys?

    I use the Live Paint option and the Live Paint bucket often.  It is really convenient to change the swatch I am using by using the left-right arrow keys to change my swatch chosen in the Swatch Palette.  But in CS6, if I am doing so, and the next swatch chosen is a percentage tint of another color (for example, I have a swatch Blue, and a swatch Blue 85%, which is the Blue Swatch tinited to 85% in the color palette and then made into a saved swatch), the "select" box around the swatch disappears, and I can no longer change the swatch choice without re-clicking on it.
    I can change easily between swatches that are not percentages of the original, with no problem.  CS5 and all earlier versions that had this feature had no problem whatsoever.
    Huh????

    All swatches are CMYK creations by me, then I choose Global.  So, I get swatches called things like, Skin Dark, Skin Med, Skin Light.  Then, I want something a tint of one of these. So in the color Palette with a Swatch chosen, I slide tint to say 50%. Then I make a new swatch ("Skin Light 50%", global). Using the arrow keys, when I get to this new % swatch, it deselects, and I can't "scroll" through the swatches, as the "white outline" selection disappears and the swatch selection stays on this % swatch.

  • Can't move an object with arrow keys - CS3

    In Fash CS3, suddenly, in certain files, I can't move an object left using arrow keys - but I can move the same object right, or if I hold down Shift + left arrow, it works correctly
    Also - I can move the object down with arrow keys, but not up
    Workaround - move an object on a different layer, then return to the problem object and it moves correctly. But this doesn't last long, the problem resurfaces.
    Does anyone have a solution for this? (I've tried rebooting; tried copying all the layers into a new file - no help.)

    Now, working in the same file, I just clicked on a stroke and it changed the stroke from a smooth curve to angular lines.
    I suspect this file is corrupt. Any thoughts on how to salvage the weeks of work that have gone into it? Every version of this file has the same issues.
    Thanks for any help.

  • How to change the presets in pop-up menus (CS6 or CR 7, example Photo Filter) with arrow keys?

    How to change the presets in pop-up menus (CS6 or CR 7, example Photo Filter) with arrow keys an see at the same time the changes on the photo?
    It worked under Windows, now I use OS 10.8 and have to apply a preset with a click or Return button but after that the pop-up menu close so I have to open it once again to change a preset. Please help. Thank you!

    The filter panel is a shortcut for the content panel and it only effects the content of that window. So if you have a folder it will only see this as a folder and not with its content. (a Stack behaves about the same, being different in only counting the first file in the filter panel criteria but not what is in the stack itself)
    You have a view work arounds, first is use menu view / show items from subfolders (this can take some time especially if you have not used caching before on this content) and this builds visible thumbs for all content and that can be used for filtering.
    Or use the find command (Edit / find) and inhere specify the source and fill in the criteria include subfolders and this will give you the correct result.
    When you create a smart collection the find command also pops up given you the same opportunity to get the results in a collection, but since a collection is only a bunch of aliases referring to the originals you might be a bit careful with editing and deleting.

  • Artifacts when moving object with arrow keys.

    Hi all
    hope this is the right place to post this question.
    I want to to write simple arkanoid game in Flash (AC3). I've managed to write code that  moves my paddle with arrow keys. The code looks like this:
    function OnNewFrame(event:Event):void
        if (input.IsLeftHeld)
            if (paddle.x > 0)
                paddle.x -= 10;
        else
        if (input.IsRightHeld)
            if (paddle.x < stage.stageWidth - paddle.width)
                paddle.x += 10;
    It works but the result is ugly. The animation is not fluent, there are times when paddle stops for a moment . Also when speed of translation is high (here it is 10) you can see that paddle is flickering at the ends, it looks like single buffering problem. You can see both of those effects here:  http://www.flash-game-design.com/flash-tutorials/movOb.html , hovewer flickering is less visible due to small translation amount.
    How to fix this? How can i enable double buffering (or maybe it is enabled by default)?  Any help will be appreciated.
    P.S. sorry for bad english

    Thanks for samples, this is very kind ; p
    Hovewer you are doing everything almost exactly as I'am doing. Tou are using mySymbol.x++ which means your translation speed is 1. Also I'am aware that rising frame rate will result in smoother animations, but this is not the point. So once again, my flash applications suffer from two problems:
    1) Animations are not smooth. You can see this crealrly in here: http://www.kirupa.com/developer/actionscript/hittest.htm  , go back to the very bottom of the page, there is an animation window, look at the smallest circle. It looks like its blinking. 
    2) Moving symbols with arrow keys with the method i've presnted in the first post (the same method that infeter uses ). Moved symbol is randomly stopping for the very (very very) short amount of time. You can easily spot this in infeter sample.
    Many sample applications i've seen suffer from those issues. and nobody seems to see the problem, so maybe I am delusional? ; p
    cheers and thank for help

  • Premiere CC Frame stepping with arrow keys

    Why can I no longer step ahead or back one frame at a time with arrow keys after updating PremiereCC software?

    It's working here for me xAndyx. Can you try trashing preference? Press Shift + Option and restart Premiere Pro (warning: you'll use any custom kb shortcuts, workspaces, etc.).
    Thanks,

  • Moving anchor point with arrow keys crashes Photoshop CC

    Hey guys,
    I've recently run into this bug many times while working with shapes. Don't really know what initiates it but it's super annoying as it crashes the PS CC completely without possiblity of recovering the unsaved files.
    The bug appears while working with shapes after file is saved and reopened. Because I use to design pixel-perfect UIs, I work with arrow keys a lot to be sure every pixel is in the right place. So after selecting one or more anchor points of shape and hitting any arrow key (to move it by pixel), photoshop immediately crashes with this super-long description of bug: http://justpaste.it/ccshapecrash
    Dunno why but this occurs very often when handling 1px-thin rectangles.
    Is it only me or has anybody else experienced this as well? Any idea what exactly is causing it or what might be wrong with my config?
    Never seen that kind of error in Photoshop before. It completely destroys my everyday workflow

    I have exactly the same problem and I don't have any solution. I was tried to update the latest video drivers - nothing! Tried to update Photoshop which updates fixes bugs - nothing! The problem continues.
    My OS is Windows 8 64bit, video card Nvidia GT 630. For the case, my Photoshop 32x works better (faster) than the 64x. Why is that ? I hope to have a solution.

    Take it to your local Apple Store or AASP, it's covered by a 1 year hardware warranty. If you have AppleCare then give them a call but I'm pretty sure they will advise the same. If you have not purchased AppleCare yet please do, this will extend the warranty to 3 years however it MUST be purchased within the first  year of ownership. Let it go 366 days and you are out of luck. AppleCare will also include telephone support too.
    Good luck.

  • How to make a first-person style game with arrow key movement?

    Hey guys, I've made some simple click-to-move 1st person games with AS3, but I just wanted to know if there was a way to move around in 1st person with arrow keys, I was thinking you could get the background to move with the arrow keys, but that would be a little confusing.
    If you guys have any suggestions for me, or if it's possible, please reply! Thanks

  • Screen Scrolls in games with arrow keys

    My kids play a lot of games online.  I can't lock the screen or whatever you want to call it.  If the game requires the arrow keys to move the character, it scrolls the screen until they can't see the game.  I have tried to click on the flash player game window but it still scrolls to the bottom of the page when you pich the arrow keys.  Any help?  Thanks!

    What is "it"? Did you create the game in Flash, or is this an online game?

  • Moving a line with arrow keys/can't adjust distance

    In Illustrator CS6 I can't adjust how far a line moves when I move it using the arrow keys. I've gone to Preferences>General>Keyboard Increment and changed the amount, but the line moves the same distance no matter what I put in. Neither Snap to Grid nor Snap to Point are turned on.

    Thank you Mike! It was driving me crazy. I just started to use CS6 and hadn't messed with any adjustments. How would someone know to check such a seemingly obscure--except to come to the forum?

  • I can no longer move an object with arrow keys

    Pretty sure I have inadvertently disabled the option to select an object and move it with the arrow keys on my keyboard, but cannot figure out what I did - or how to enable that option again.
    Illustrator CC
    27" iMAC late 2013
    OS 10.9.5

    Found the answer in another thread. Somehow my keyboard increment was changed to a measurement so small (.00002") that I couldn't see the object move, nor did the X & Y coordinates change. I did not change this preference to .00002", but it is now fixed.

  • Traverse JTable cells with arrow keys?

    I want to be able to use arrow keys to travel in the matrix. But I want to restrict entering column 0. That is, the user should not be able to enter column 0, with the arrow keys (and neither using the mouse). Anyone have hints how to do this?

    Well, the problem is that I have a viewport into a big matrix. The user is able to scroll the viewport around.
    I must be able to figure out if the user is pressing the arrow buttons to go outside the viewport, because then I have to change the viewport. Somewhere, there is a class that knows the current cell that is highlighted. I must check that class to see what direction the user wants to go with the highlighted cell.
    And, also, the user is not allowed to enter column 0. If he wants to go column 0, then the viewport will be scrolled.
    So my question is, which class knows which cell is highlighted? The Jtable, probably? Which methods?

  • Moving shape with arrow keys

    A couple of notes:
    - That code did not add the keyListener to anything.
    - At the moment (in the altered code below), only the blue circle moves, and only left/right. It is left as an exercise to the OP to 'take it from there'.
    - It only took four more lines of code to turn that code into an SSCCE*, which will generally get more help.
    - Please use code indentation, and the code formatting delimiters, when posting code. It makes code a lot easier to read and understand.
    * The SSCCE is described at..

  • VoiceOver conflict with arrow keys ??

    I have just found that VoiceOver is in conflict with the Up/Down/Left/Right Arrow keys. If it is on the four keys do not work. I tried another keyboard to check whether it was a hardware problem and exactly the same happened with VoiceOver on. Why?
    Until yesterday everything worked fine but suddenly I lost the arrow key functionality. Any ideas, anyone?
    Note: I am not referring to the number pad and its keyboard mouse keys.

    Hello Helen,
    First of all, VoiceOver makes very heavy use of arrow keys, so you are right in suspecting that this is an oddity, and not a "feature" of VoiceOver.
    I've managed to reproduce this behaviour with the following sequence:
    1) Turn VoiceOver on (Cmd-F5).
    2) Activate QuickNav (left and right arrows simultaneously).
    3) Interact with an element containing only one item, via down + right arrows.
    4) Arrow keys will only "bong". No movement possible until QuickNav turned off again. Otherwise, turning VoiceOver off will also restore the arrow keys to normal—until it's turned back on again, when it will once more get "stuck". Of course, stopping the interaction via left+down arrows also restores free movement—but with QuickNav active, only the VO cursor moves, not the focus, so that can be disconcerting when trying to navigate menus, etc.
    So the solution may be to turn VoiceOver on, then ensure QuickNav is off (left + right arrows), then VoiceOver off again.
    Hope this clears it up!
    Archie
