Nearly everything can be edited somehow in a Linux system, and that includes what each key press does. The gHacks blog shows us how to create global application shortcuts that fire up Firefox, a text editor or anything you'd like.
You can change a few of your keyboard shortcuts from the standard System->Preferences menu offering, but opening up the GNOME configuration editor, as gHacks details, lets you create universal shortcuts for applications, scripts or other items to run from anywhere you hit the keys:
- Hit F2
- Enter gconf-editor to start up the tool.
- Navigate to Apps > Metacity > keybinding_commands.
- Right-click in the pane that lists all of the entries.
- Scroll until you see a list of command_N Where N is a number from 1-10
- Double click on one of these entries (remember which number you double clicked on).
- In the Value section enter the command you want to use.
- Click OK.
- Navigate to Apps > Metacity > global_keybindings.
- In the Value field enter the key combination you want to use for that app (for example f for firefox).
- Click OK.
- Test out your short cut.
You don't want to tie up keyboard shortcuts used in other apps, of course, like Ctrl+Z, but there are probably a lot of users who can save at least a little time with such a trick.
