My laptop is a Thinkpad. I tried to map the bindsym to the function keys so I can easily call some applications. Since the Thinkpad is using the function keys to map the other functions, users need to press Fn + functionkey at the same time. What I meant is, if I want to press F1, I need to press Fn+F1; otherwise pressing F1 in my laptop will mute my speaker instead. So I use xev to check the keysym. F1 key is "XF86AudioMute". F2 key is "XF86AudioLowerVolume" and etc. But F4 doesn't return a keysym. So, does that mean F4 can't be used?Sat, 03 Nov 2012 02:06:31 +0000https://faq.i3wm.org/question/719/using-xev-to-check-the-keysym/https://faq.i3wm.org/question/719/using-xev-to-check-the-keysym/?answer=723#post-id-723This is what `xev` returns on my X220: > KeyPress event, serial 32, synthetic NO, window 0x2000001, root 0xb2, subw 0x0, time 10473642, (96,319), root:(99,411), state 0x0, keycode 70 (keysym 0xffc1, F4), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False > KeyRelease event, serial 32, synthetic NO, window 0x2000001, root 0xb2, subw 0x0, time 10473737, (96,319), root:(99,411), state 0x0, keycode 70 (keysym 0xffc1, F4), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False Maybe the key is being grabbed by another application?Sat, 03 Nov 2012 04:01:53 +0000https://faq.i3wm.org/question/719/using-xev-to-check-the-keysym/?answer=723#post-id-723
