This might not be Mathematica specific question but if there is anyone who can use Emacs keybind on Ubuntu Linux, would you share how you realize it?
I'm using Mathematica student edition both on Mac OS X (10.7.3) and Ubuntu (11.10), and Mac version allows basic Emacs keybind (Ctrl+a, Ctrl+e, Ctrl+d, Ctrl+f, Ctrl+b, etc.) In general, GUI programs on my Ubuntu doesn't allow Emacs keybind unless explicitly configured per program, so as I said I might have to look for general solution for Ubuntu/Linux. But I welcome whatever the solution to realise the keybind.
Update: Thanks to @sebhofer's answer, I manage to comfortably use Emacs keybind on Ubuntu. I had to modify both
KeyEventTranslations.tr to enable my preferred keybind.
C-v "ScrollPageDown" C-d "DeleteNext" C-h "DeletePrevious" C-p "MovePreviousLine" C-n "MoveNextLine C-b "MovePrevious" C-f "MoveNext" C-t "MoveNextWord" C-i "MovePreviousWord" C-e "MoveLineEnd" C-a "MoveLineBeginning"
Some of the above might not be the standard Emacs keys. Also, more importantly, some default keybinds that use alt might not work due to the change (I haven't tested thoroughly). You can customize by modifying those
