I got one of these cheap keyboards for a laugh:
It's a 61-key keyboard with some Fn function keys like a laptop.
They come with a manual which explains most of the operation but not all.
It appears in lsusb as:
ID 04f3:152e Elan Microelectronics Corp. Gaming KB
- FN+r = Volume Down (XF86AudioLowerVolume)
- FN+t = Volume Up (XF86AudioRaiseVolume)
- FN+y = Volume Mute (XF86AudioMute)
- Fn+u/Fn+j = Increase/decrease the speed of the RGB light disco (5 levels)
- Fn+o/Fn+l = Increase/decrease the backlight brightness (5 levels)
- Fn+k = Change the pattern of the RGB disco (smooth slow, smooth fast, steps)
- Fn+m = Cycle through individual solid colors with no rotation
- Fn+i = Backlight on/off toggle
- Fn+` (backtick) = Esc
- Fn+1 = F1
- Fn+2 = F2
- Fn+3 = F3
- Fn+4 = F4
- Fn+5 = F5
- Fn+6 = F6
- Fn+7 = F7
- Fn+8 = F8
- Fn+9 = F9
- Fn+0 = F10
- Fn+- = F11
- Fn+= = F12
- Fn+Backspace = Delete
WASD have arrows, but they are not activated like regular Fn keys.
To switch these into arrow mode, press Fn+w.
The WASD keys then become arrow keys without need to press Fn anymore.
To switch back to WASD mode, press Fn+w again.
The Win or Super key has a padlock on it, implying some sort of lock.
Pressing Fn+Win disables the key altogether.
Enable it again with Fn+Win.
- There is no Home, End, Print Screen, Pause, PgUp, PgDn, Insert
- Insert is a bit of a dealbreaker for me, because one of the Linux clipboards is commonly accessed by Shift+Insert to paste. Map Menu to Insert with
xmodmap -e "keycode 135 = Insert" - Hiding Esc under Fn is awkward for Vim, I used keyboard settings to rebind Caps Lock to be another Esc
- The placement of \ (backslash) and Enter is not to my liking, I prefer backslash/pipe above Enter next to [] (square brackets)
- The behaviour of the Win key is rather absurd and useless. Why even bother?
- This is NOT a mechanical keyboard, it's a membrane keyboard. I am fine with that and didn't expect it to be, but some people have been tricked by shady marketing of "mechanical style" which just describes the look. You're not going to get a mechanical keyboard for US$20.
