How can I change the behavior of a key?
Hi. I have bought a new Macbook Air on the US, and I configured it to use a Spanish keyboard layout.
When I press alt+the button left to 1, I want a backslash \, but I'm getting a ≤ symbol.
How can I change this?
Thanks
Hmmm, I don't really see how to do it there, since that is for assigning keyboard shortcuts for menu functions.

How can I change the behavior of the pulldown history list?
When you click on the little down arrow between the star and the clockwise arrow on the address bar, it seems to list the previously viewed websites in some kind of frequency of access order.
Is there a way to have this pulldown work like IE does? That is, show me the last 20ish sites I typed in without regard to how often I have visited the site?If you want to get 20 sites in the address/location bar (when you click on the little down arrow between the star and the clockwise arrow) go to [http://kb.mozillazine.org/About:config About:config] , find [http://kb.mozillazine.org/Browser.urlbar.maxRichResults browser.urlbar.maxRichResults] and change the value to '''20''' (right click on it, select modify and put the value you want), exit firefox and restart it.
thank you -
When using Firefox for Andriod:
When filling out a field on a form, they keyboard has a Green Enter button that submits the entire form. However, there are multiple fields on the page, and I would like it to tab to the next field. At the very least not submit the form.
Also, is there a way to configure the keyboard that shows up for each html5 input type?They keyboard that shows up has the large "Green Enter" go button, a backspace and some arrow keys, but no tab button.

How can I change the display of Inbox in my iPad's mail app- so that it takes up the whole screen, as opposed to just about one third; the other two thirds display the full text of the selected email?
You can't change the display in the Mail app, if you are holding the iPad in landscape orientation then the left-hand third will be for navigation, and the right-hand two-thirds will be an email. If you hold the iPad in portrait orientation then the navigation section becomes a drop-down section.

How can I change the background of a running webpage on my own. Example Facebook I want to change its background color from white to black just in my view, not for all. Cause I really hate some site with white background because as I read for an hour it aches my eyes but not on those with darker background color.
You can use the NoSquint extension to set font sizes (text/page zoom) and text colors on web pages.

Is it possible to save the screenshot files to a different folder than desktop (that is the default). How can I change the destination folder? Thank you, Sal
To change the screenshot capture location to a new place on your Mac, first think of a location that would serve you properly. We like to place ours in a "Screenshot" folder located inside of the User's "Pictures" folder. To change the location to this new location, open the Terminal and enter the following command:
defaults write com.apple.screencapture location /Users/[u]/Pictures/Screenshots/
Replace "[u]" with the name of the user on your system. Once you have entered this command, let's restart the screen capture utility by restarting the SystemUIServer by entering the following command:
killall SystemUIServer
You can optionally log out and back in instead of entering this second command, thus restarting the SystemUIServer. Once restarted, all screen captures taken from here on out will end up in your /Pictures/Screenshots/ folder in the User's home folder on your Mac. -

When my husband and I first bought our iPhones, I was the only one with an Apple ID (since he never used iTunes). He used my apple id to get apps. Now he has his own ID, but my apple ID email address keeps popping up on his phone when he tries to download an app. We do not want to have all of the same apps on our phones. How can we change the ID on his phone? I already tried going to Settings>iTunes &App Store> and changing the Apple ID to his account email and that did not solve the problem. To make things worse, I recently changed my Apple ID email address (without getting a new ID) and I do not remember my old password (and this is the address that is popping up on his phone). He does not have any music on his phone and all of the Apps that he has are free. Any help you could offer would be great (-:
All apps are forever tied to the Apple ID that bought them. To stop your id from popping up, you need to delete the apps on his phone, and then repurchase them under his account.

I have both Photoshop 4 and Photoshop 6 on my computer. When I am in Bridge and want to open an image by double clicking, it automatically opens in 6. I see, when I go to "open with" 6 is listed as "default" How can I change the default to open an image with a double click in 4?
You can associate files from the Bridge level and the Desktop level.
In Bridge CS4, go to Preferences > File Type Associations and change it to Photoshop CS4 for the file types you want.
If you want to open files from the Windows Desktop in CS4, these are the instructions:
Do this from the Windows Desktop:
If you want your image file to open in Photoshop and it doesn't, right click on it and choose
Open with > Choose default program… select Photoshop CS4 or CS6 and checkmark "always use the selected program to open this type of file". -
How can we change the password in the iBook donated to our nonprofit? No password was given with the iBook and every time we try to install items, the password window pops up. We need to put in printer and other software. Help! We can use the laptop without changing the password.
If you did not get an OS X install-restore DVD with the computer you may need
to buy one from somewhere, and you may be lucky to get a retail OS X 10.5.x
version. The original grey-label install set of software and OS X it shipped with
likely would be an older system than Leopard 10.5. Last versions of G4 Mac, &
G5, shipped with a Tiger 10.4 system; so did early Intel-based Mac. Grey discs
which accompanied other computer build models generally do not interchange.
The last OS X version a PowerPC architecture can use, if supported, is 10.5.8.
A PPC processor at 867MHz & faster should be able to run OS X 10.5 Leopard.
{With the correct disc installer, you can use it to change a password and other
things including re-install, and perform disk utility functions, etc.}
There is a chance you may be able to get a white-label Replacement 10.4 DVD
or Replacement 10.5 DVD from AppleCare or the online Apple Store (800myapple)
from a Mac OS X system specialist; these have been available yet hard to get
as not all persons involved with them seem to know if they still exist until someone
is asking. These aren't retail stock, are special discs for computers who could use
a system later than original old discs; these are complete install discs not for one
specific series of Mac. Generally they'd work in supported PowerPC G4/G5; but
do not replace specialized original install DVD, such as an early Intel mac requires.
You'd need to have a serial number of the computer, and a method of payment
when seeking some replacement system media from Applecare or Apple sales
and these discs are not available in a retail store. The original Retail discs are
labeled differently and shipped in a retail box with a big X on the front. Other
sources for retail 10.4 Tiger or 10.5 Leopard may be online via amazon sellers
or computer resellers who handle repaired Macs. Avoid mystery grey label ones
that were intended to be sold and kept with their original computer kits.
Good luck! -

How can I change the name of item in TableViewController iOS
How can I change the name of item in TableViewController? I want to be able to change the title of an item if I added one. Code:

Sounds like you have more going on than just a simple issue with Home Sharing and more dealing with Wi-Fi syncing. Start with the article below and see if that may resolve it.

If it does not work out, then may I suggest contacting Apple for further assistance to walk you through it or just take that time that you were talking about to sort it out.

How can I change the settings wit mail so that when I delete my Verizon email from my iPhone it will also delete from my iPad too.... Seems like I shouldn't have to delete my email in three places...iPhone ..iPad ...and desktop
Don't know which email host you are using, but if this is a POP account, you can't do it. If IMAP, then deleting one email should delete it on all other devices.

How can I change the pitch of a track?
In Garageband 10.03, how can I change the pitch of a track?
It seems that I somehow mistakenly changed the pitch of a guitar track I had recorded, so that al the notes in the track sound like they're about an octave too high.
I don't know how I did that, and how to make the pitch slider appear so that I can try to lower the pitch.
I saw three Youtube videos that show how to change a track's pitch by using the pitch slider, but none of them explain how to make the pitch slider appear.
The pitch slider is supposed to appear in the lower, left corner of my window, but it doesn't appear in my window. Instead the lower, left corner of my window says things like, Region, Notes, Time Quantize, Strength and Transpose.There's much to learn in Garageband!
If you want a comprehensive introduction to the new GarageBand, have a look at Edgar Rothermich's book:
Edgar's "GarageBand 10.0 How it Works" explains it very well with many screenshots. You can buy it as iBook from the Book store, as PDF, or as printed book from Amazon, Only, this version of the manual has been written for GarageBand 10.0.1, Some features have changed slightly since then.

How can i change the column label text in a alv table display
how can i change the column label text in a alv table display??
A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
<i>* declare column, settings, header object
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
get column by specifying column name.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( ' ' ).</i>
My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
<i>"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."</i>
i have checked in debugging and the error occured at the statement :
<i>lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).</i>Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
Thanks,
SuriI found it myself how to do it. The error says that it is not able to find the reference object i.e it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,
lr_if_controller TYPE REF TO iwci_salv_wd_table,
lr_cmdl TYPE REF TO cl_salv_wd_config_table,
lr_col TYPE REF TO cl_salv_wd_column.
DATA : node_year TYPE REF TO if_wd_context_node,
elem_year TYPE REF TO if_wd_context_element,
stru_year TYPE if_alv_layout=>element_importing,
item_year LIKE stru_year-i_current_year,
lf_string TYPE char(x),
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_header TYPE REF TO cl_salv_wd_column_header.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
Get the entered value from the input field of the screen
node_year = wd_context->get_child_node( name = 'IMPORTING_NODE' ).
elem_year = node_year->get_element( ).
elem_year->get_attribute(
EXPORTING
name = 'IMPORT_NODE-PARAMETER'
IMPORTING
value = L_IMPORT_PARAM ).
WRITE L_IMPORT_PARAM TO lf_string.
Get the reference of the table
lr_cmp_usage = wd_this->wd_cpuse_alv( ).
IF lr_cmp_usage->has_active_component( ) IS INITIAL.
lr_cmp_usage->create_component( ).
ENDIF.
lr_if_controller = wd_this->wd_cpifc_alv( ).
lr_column_settings = lr_if_controller->get_model( ).
get column by specifying column name.
IF lr_column_settings IS BOUND.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME').
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( lf_string ).
endif.
