Navigate JTable using Ctrl and arrow combination

By default, one way to navigate cells in a JTable is by using the arrow keys. I need to change this so that the user must hold down the Ctrl key and then navigate with the arrows. The arrow keys alone will not have any cell navigation functionality... they will only be used for editing cells that contain a JTextField (or some variant).
Can anyone help me with this? BTW...I am using jdk 1.4.1_03

To answer my own question:
Using the InputMap and ActionMap of the JTable, the keybindings can be removed or added, so for moving one column to the right by holding down CTRL and pressing the right arrow, it is as simple as:
InputMap inputMap = table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
// KeyEvent.VK_RIGHT is the right arrow key, and 2 is the CTRL key mask
inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_RIGHT, 2), "selectNextColumn");Here are some links that were of help:

I have drawn some maps in pages using shapes and arrows. When I delete a shape a little grey dot appears that cannot be deleted. Any ideas?

I am using shapes and arrows to create concept maps in Pages. After saving the document I have opened it again and tried to make changes.
When I delete an arrow or shape a grey "Do not" sign pops up. It cannot be highlighted or deleted. My map now looks like it has grey measles.
Any idea what is happening?

Hi Kiku,
Select all the objects that you want in your map.

T42p + Access IBM - my mouse fails-only use TAB and arrows? XP desktop

Suppose to be like day one here, my Thinkpad T42p but when I press the BLUE button or the Access IBM Icon
my mouse fails-I can only use TAB and arrows and I am NOT in the post bios, I am in the XP desktop.
I uninstalled and reinstalled it, but no help, same with USB mouse, same with touchpad and same with the red
pointer button mouse.I was almost SURE that the other Thinkpads, same models, would have mouse ability.
How do I fix this mess? What happened ? Help !! Have you tried to use that tool with no mouse ? Aggggggh !

Download a Parted Magic CD ISO-file and burn it on a CD-ROM.
Boot from CD-ROM and run the partition tool.
Left-click the 1st Partition, select "Manage flags" and mark "boot".
Reboot the computer after removing the CD-ROM.
To remove the drivers and tools use "Start"- "Programs " - "Access IBM" - "Program for installing/removal of ThinkPad-Software" (or similar - i only know the german terms). - Later Thinkpads used the "Software Installer"
At the beginning of this year i had set up one of my R51 with the recovery CDs and ran all Windows Updates. - Everything worked fine then.
Just for fun and to learn the effects concerning the system stability, i installed Thinkvantage System Update and updated all drivers and Tools. Some updates didn't work.
Result:
- lower performance
- wireless didn't work anymore
- sometimes a blue screen running R&R
After that i recoverd the R51 again and removed all Access IBM tools and drivers with the "Program for installing/removal of ThinkPad-Software". Running TVSU then lead to a better result but not very satisfying.
The differences of the old driver and tools - versions to the newest is too big. A lot of registry entries and many files will be kept after removing the old drivers and Access IBM - tools.
The best result you will get using one of the following ways:
recover from CD/R&R-partition and keep all TVT drivers and tools
do a clean install from a Windows CD and install drivers and software after running all Windows Updates (only 1 GBit ethernet or wireless Lan- driver installed) and then use System Update or manual install

Why can't I use 'Control and Arrow' to zoom with Leopard?

Hi guys,
I've lost the ability to quick track zoom since installing Leopard. When I press Control and one of the four vertical or horizontal arrows, the Spaces icon shows and shoves my Logic out of the way.
I hope that there's some way to disable this function so it will enable me to use my beloved Zoom again.
Please help!!!

Bridge cs6 . I can't select more than 1 file even when I use ctrl and select a few files. Bridge will just open them indivudually.It was working properly a week ago.

I cannot open multiple files on Bridge cs6 on my pc. I hold down ctrl. but it just opens them individually. This function was working in the past. caps lock is off, nothing has changed....help.

As I select a file, it will launch its application automatically. Therefore I can not select multiple files or just single files without opening the application.
I did not have this problem before. I started having this problem after I updated my system to OS X Yosemite.
I tried to reset Bridge preferences, installed updates, but nothing worked so far.
Can anybody help?

My desktop display has been magnified and everything I open is similarly magnified.When I try to zoom out using Ctrl - or the mouse nothing happens

My MacBok Pro suddenly magnified the desktop display significanlty. All programmes and applications are similarly magnified when open. I tried zooming out using Ctrl - and I also tried holding down the Option key and scrolling down using the mouse. Nothing happens to zoom out of the desktop and on Facebook for example the columns get smaller but the text doesn't so lines of text end up overlayed each other. What can I do to remedy the situation?

Found the Option key. Googled it. And yes your instructions worked a treat. Thanks

How do i use numbers for image gallery and arrows?

Hello there,
I'm hoping someone can advise me on the best possible way.
I would like to use numbers to help the user navigate through the image gallery i'm creating and arrows on either side of an image (one image viewed at any one time). I have attached an image of what i'm trying to acheive. I feel like the arrows will help aid the user to navigate and the numbers will inform them on the number of images to view.
I have so far created the site with a template (logo and nav bar) and child pages for: home/about/work/contact.
Hope to hear from someone soon.
Nicola

With so many pre-built image galleries available to you, there's no reason to re-invent the wheel.

Re: Why don't my arrows on the time line operate and allow me to move to the start and end of the timeline. Iam using the trial version

Check System Preferences. I think Control-1 is used by something in the OS now. Switch it off. It's a major p[ain the way the OS is taking over more and more of the keyboard, allowing less options for application use.

Key binding won't work with alt-up and alt-left arrow combined

I was playing with key binding trying to create a small app where a timer is started with the press of an alt-arrow key and stopped when the key is released. The timers append Strings to a JTextArea telling which alt-arrow key is currently pressed.
This program works, and in fact if you press a combination of any two keys, both timers will work simultaneously, that is unless you press both up arrow and left arrow together. Can anyone see a bug in the program that explains why it won't work for these two particular keys when combined? Thanks in advance, Pete

Yes indeed. I suppose (as always) I should have searched the forum first before asking the question. Thanks for the link and info.

I have itunes directory on an external hard drive and want to direct a new installation of itunes on windows 8 to use it. I tried holding down ctrl and clicking itunes and after many tries got it to work one time. When I went back in later it had reverted back to a blank version of itunes and I cant get ctrl to work again. Any other ideas?

This is sometimes caused by a problem with the iTunesPrefs.xml file, normally found at C:\Users\<User>\AppData\Local\Apple Computer\iTunes\iTunesPrefs.xml. Try dragging this to the desktop and trying again.
Alternatively the problem may be that you have McAfee AV and it is preventing iTunes from updating the same file and thus causing the problem. See Why does iTunes delete my itunesprefs.xml? for details.

Some of the shortcut keys and directional keys on the keyboard are not working in FF 4 RC1 (i.e. Tab, Ctrl+C, arrow keys). They work fin in FF 3.6x and other applications.

Crtl+C, Ctrl+V, Ctrl+X, Tab, and arrow keys do not work at all in FF4.0b13 and later. I am not sure about earlier versions as this is the first version I have tried.

I found this helpful article (http://support.apple.com/kb/TS1381) and worked my way through the section "Some keys don't work as expected".
All the following functions/settings are disabled or turned off:
Text to speech / Speak selected text when the key is pressed
Slow Keys
Mouse Keys.
The keyboard viewer just confirms my list of keys that are not working.
Starting in safe mode makes no difference; nor does booting from the Mac OS X Install Disc and running Terminal from the Utilities menu. The same keys as before fail to work.
This seems to confirm that it's a hardware issue. Anyone have any suggestions?

Hi. After loading a picture into Photoshop some of the menu tools are greyed out and I cannot use the keyboard short cuts, for instance I cannot use Ctrl + T for free transform, how do I resolve this problem. In addition the tool Icons are so small I have to get close to the screen to see them, is there anyway the Icons can be made bigger without reducing the resolution of the screen.
Thanks

Are you working on a background layer? If so, Ctrl + T will not work. Press Alt and double-click your background layer to convert to a normal layer (or right-click BG layer and select Layer from Background) and try again.
If you're working in Photoshop CC 2014 you can go to Preferences > Experimental Features and tick "Scale UI 200% for high-density displays" to make your buttons and icons larger.

I'm wanting to use the "Actions" in Photoshop Elements 11. But when I get the Actions box up, it is only showing a small list of effects to use. And no side bar to go any further. When I click on the little arrow at top and then click on "load actions"

I'm wanting to use the "Actions" in Photoshop Elements 11. But when I get the actions box up, it is only showing a small list of effects to use. And no side bar. So I can't go any further. When I click on the little arrow at top and click on "load actions", I am only getting a box with empty space saying "No items match your search". The folder at the top does say "Actions". How do I get more effects? The tutorials that I've checked into all show a long list of effects in their box. Can anyone help?

To use the existing actions, try the following:
1. Open one of the Action Sets, in this example Special Effects is the Action Set, by pressing the small arrow beside the set name.
2. Then click on the name of the Action, in this example Faded Ink is the Action name.
3. Then press the Play button to run the action.
