how can i create a keyboard shortcut for a certain application i want?
for example.. xchat can be executed by typing xchat in the terminal..
is there a way to execute xchat by just pressing .. CTRL + X ? how?
im using redhat8
thanks!

in kde, open up your menu editor and find the program you want to assign a hot key combo to. there's going to be a little button on the right that says current keyboard shortcut. click that button and then type in your key combo. to get to the menu editor in kde, right click the kstart button and choose menu editor from the context menu. i'd advise using ctrl+x (or any other ctrl+"alpha_key") as those are pretty much used for some things already - ctrl+x is cut selection to clipboard (kinda like ctrl+c is copy selection to clipboard, ctrl+v is paste from clipboard, etc...) although you can change this in the kde control center under accessibility. i guess maybe you should have control center open while doing this so you can see which shortcut keys are already taken and decide if you want to make wholesale changes.

if you're using gnome, i'm not going to be able to help you there as i very, very, very rarely ever use gnome.

id say do CTRL SHIFT X would be better if u can do that.

better than pasting when u accdently push x, lol.

im using gnome ;(
is there a way?

run
$ gconf-editor

go to apps >> metacity >> glogal_keybindings

associate the sequence of keyboard you want!

right click, Edit Key or, if you want, New Key
in Value field type the sequence.
for example: <Alt>F8 or <Control><Alt>F8

select now keybinding_commands
in the command you edited right click and type the command in value field!

That's all!

Enjoy!
