When I compile a pdf document in texmaker, I often press Alt+Tab to swich to the external pdf viewer.
If at that point the cursor in texmaker is by coincidence at a position where texmaker can make an auto-completion, pressing Alt will show the options for auto completion, pressing Tab will highlight the first option and releasing both will select the first option.
This can be very anoying when the cursor is in the middle of a complicated formular. Is there a way to prevent texmaker to missunderstand the Alt-Tab command without swiching off auto-completion completely? I am using Texmaker 4.1 on Ubuntu 14.4 LTS.
