Using current Xubuntu 16.04LTS, wxmaxima 15.08.2 (and tested git-based wxmaxima 16.04.2 too).
It ignores some keyboard shortcuts, like "Ctrl+1" for text-cell insertion (contrary to "Ctrl+2" that works correctly); and "Alt" key seems to be ignored totally. Not being sure whether it is on wxwidgets, wxmaxima, or xfce.
