* Run `cat`
* Open search box
* Press Up/Down/Tab key
Actual result: keys are sent to `cat`
Expected result: nothing should happen (implemented)
Alternative expected result: focus should move from text input to first
button
Regression test:
Following keys/shortcuts should work:
* Shift+Up/Down/PgUp/PgDown - terminal contents scrolling
* Ctrl+Shift+T - open new tab (unless it was changed)
* Enter - search next
* Esc - close search box
