Alttab runs on every device that can run X11.
It's trivial with Linux phone (Pinephone, Librem, Pro1-X, Volla).
With Android, alttab runs fine in Linux chroot displaying in XServer XSDL.
Using -e
option, an external program can pop up the switcher:
alttab -e &
xdotool key alt+Tab
This is particularly useful with Linux phone and gesture daemon. To call alttab by swipe to the right at the left screen edge:
alttab -mk Control_L -e &
lisgd \
-g '1,LR,L,*,/usr/bin/xdotool key ctrl+Tab' \
...other lisgd options... &
