If there's actually, legitimately, a "stuck key" in Inner Space/ISBoxer then simply tapping that key or switching away and back to the game window will resolve the "stuck key".

However, if the problem persists or "only happens on keys I added", that's probably not it. I'd say it's PROBABLY due to enabling either the Hold option, or the "Use FTL Modifiers" option, for the Mapped Keys in question. That typically can't be done just by using the Mapped Key Wizard, because an "Assist and Broadcast" from this wizard does not give you the option to enable either of these two things for the new Mapped Keys... so you probably manually enabled one of these two things either on an entire Key Map, or on multiple Mapped Keys. The only way to resolve this problem is going to be to undo that change.

To explain the issue, the Assist part is done by pressing Shift+Backspace (if you're leading with Slot 1 or 2 at the time; Left Shift+Backspace for Slot 1, Right Shift+Backspace for slot 2, Ctrl+Backspace for slot 3, etc -- fpsware: this is a good reason why you'd sometimes see Ctrl but mostly Shift. This sounds just like your issue as well.) prior to sending the "1" key or whatever you're wanting to Assist and Broadcast. If you enable "Use FTL Modifiers" this option purposefully adds the FTL modifiers to EVERY keystroke in the Mapped Key -- that's the Shift or Ctrl in the Shift+BackSpace -- so it becomes instead Shift+Backspace followed by Shift+1. If you enable "Hold" this option purposefully holds down EVERY keystroke in the Mapped Key -- so instead of Shift+Backspace followed by 1, or Shift+Backspace followed by Shift+1, it becomes Shift+Backspace+1 all at the same time.


If you would like me to be more specific about what you need to do to fix your particular configuration, I would need to see it. In ISBoxer go to File, Copy ISBoxer Toolkit Profile to Clipboard, then go to privatepaste.com, paste it there ("Save Paste"), and give me either the link to it or the Paste ID
