xdotool (fake X11 keyboard/mouse input)

This tool lets you programatically (or manually) simulate keyboard
input and mouse activity, move and resize windows, etc. It does this
using X11's XTEST extension and other Xlib functions.

Example: focus the firefox url bar

xdotool search "Mozilla Firefox" windowactivate \
        --sync key --clearmodifiers ctrl+l
