Bug#660370: Experienced this as well

[Thomas Goirand]

Hi,

I just saw that too, and wanted to report, but checked on some already
reported bugs.

What I saw is that you need to create a new terminal tab, then pressing
ALT-2, then ALT-1, the terminal gets the keyboard focus again. This
happens after switching from one window to another as well (I can't
remember if it was with alt-tab or switching with the mouse though).
