 - You can theoretically block any key on a keyboard that registers as a standard keypress. This includes weird special keys like a volume wheel. You might want to set volume wheels to threshold of zero if you have one. Extremely specialized keys (such as G Keys) might not be standard keypresses and thus not be blockable. If in doubt: try it and see!
 - You can block mouse buttons if you want (Left/Right/Middle/Forward/Backward). Be careful if you block left mouse button chatter: if you set the limit too high, you might become unable to double-click. If you get stuck, you can either uncheck the `Enabled` box to regain control and fix that, or, if needed, use Task Manager to kill the blocker program, and then edit the config file (see config notes below).
+- You can manually edit your config to add `wheel_change` key detector, if you have a counter-scroll/wheel bounce issue similar to what's described in [issue #17](https://github.com/mcmonkeyprojects/KeyboardChatterBlocker/issues/17).
 - This only works in user-space. That is, the Windows login screen and other sensitive Windows protected input areas will not have chatter blocked. You might want to use a PIN or other login method to avoid chatter problems that affect a password login (see also [issue #7](https://github.com/mcmonkeyprojects/KeyboardChatterBlocker/issues/7)).
 - You can add a list of programs that will cause the blocker to automatically disable when those programs are open. This is useful for example with games, as you often don't want rapid keystrokes blocked while gaming. This will be matched by executable name.
 - If you play online games, be careful that some anticheat software may block you for running this software, as it does control and alter keyboard input from software, which likely appears similar to cheat programs. See also [issue #15 which reports a VAC ban in CSGO from running KeyboardChatterBlocker](https://github.com/mcmonkeyprojects/KeyboardChatterBlocker/issues/15).
