It's a workaround for broken G613 Logitech keyboards (possibly other keyboards too) whereby some keys occasionally register multiple keystrokes for one kkkkkeypress. The key bug appears because keyboard registers multiple keystrokes in a very short timespan even though you pressed the key only once. This script makes it so the subsequent keystrokes registered in a very short timespan are ignored thus outputing the key only for the first stroke.
You need install AutoHotkey (Windows only). https://www.autohotkey.com/. A software to hijack keystrokes and assign them different functions. Then download the G613 Keyboard Fix.ahk file above, change the configuration in it, save and then double click it. You can add this file to Windows autostart if needed.
There are two variables that affect the script. The first one brokenKeys is mandatory to be set to fit your scenario. The second one fixOffset is optional:
Line 8: brokenKeys
Set this variable so in the quotes there are only your broken keys listed.
Line 16: fixOffset
You can leave as is or just to fit your requirements for auto repeat requirements (read comments in code).
Problem with this keyboard is discussed on various forums. https://www.reddit.com/r/LogitechG/comments/b8pqj9/g910_double_typing/ https://www.reddit.com/r/LogitechG/comments/fstryp/g910_keyboard_keys_double_typing/ https://www.reddit.com/r/LogitechG/comments/cu1uaa/ghub_causing_random_keypresses_or_ghostkey/
Above links suggest also other possible solutions (none worked for me, hence the script above).
- Take your keys out and clean you keybard connections,
- Change USB socket to which the keyboard is connected
- Type your broken key like crazy for several minute until it fixes itself (some folks suggested it cleans the rust)
- Quit or uninstall G-Hub
- Go to Control Panel > Keyboard and change Repeat delay to longer one. Also can try to change slower Repeat rate.
