Hello!
I found out a solution for the Alt-Gr issue.
Open /usr/local/Wolfram/Mathematica/7.0/SystemFiles/FrontEnd/
TextResources/X/KeyEventTranslations.tr file on your system.(eg.: sudo
nano ..., paths may vary).
Then somewhere under "EventTranslations[{" type some newlines, then
paste this literally:
Item[KeyEvent["ISO_Level3_Shift"],
FrontEndExecute[{FrontEnd`NotebookWrite[FrontEnd`InputNotebook[],
Sequence[], After]}]
],
This code translates the Alt-Gr key(ISO_Level3_Shift) to produce
something in the notebook, which is in this case nothing, becase
Sequence[] evaluates to nothing, albeit its syntactically correct.
Restart mathematica, and enjoy its once again slow interface under
Linux :(
i used version Mathematica 7.0.0, kernel 2.6.27, 64bit, Arch Linux, X.org
v11.0.
by the way: you can define shortcuts in this file easily.
