Hi,

I'm trying to resolve a bug I have with emacs on Ubuntu 
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26104) where pressing the 
Alt key alone produces a 'switch-frame' command, messing up commands 
like 'yank-pop' or 'dabbrev-expand'. I'm trying to figure out how emacs 
gets commands from xwindows.

One thing I noticed is that xev (e.g., if I type 'xev -id ...') does not 
catch most emacs keys (e.g. alphanumeric keys, Ctrl, TAB, shift) but it 
does catch the Alt key. Can someone explain why that is and where emacs 
sets that up (I realize it is likely in the C code)?
