Comment 0 for bug 1859400

works as expected:
(keycode 110 = Home)
xmodmap -e "keycode 110 = a a a"
    press F1 in kate or on konsole:
    (returns 'a')
xmodmap -e "keycode 110 = Home Home Home"
    press F1 in kate or on konsole:
    (cursor positions to full-left of line)

    ie: the above works perfectly

    but after binding:
xmodmap -e "keycode 110 = F1 F1 F1"
    and then reverting
xmodmap -e "keycode 110 = Home Home Home"
    Home key no longer functions as expected. (it does something, as the cursor changes for no apparent reason, but I can't figure out what it's doing)

NOTE:
I have a global KDE hotkey set to F1, that runs a context sensitive bash script (the active window determines what happens, mostly it uses xdotool to determine window title and then writes a timestamp into a text file)
