is there a maximin amount of simultaneous keypresses?
I was playing arc Raiders and couldn't run and jump at the same time (W, Lalt and spacebar) I rebound jump to my mouse and it works fine
TZMK keyboards don’t generally have a “2-key only” limit like old office boards; they should be able to send multiple simultaneous keypresses.
For the specific combo W + LAlt + Space, the most common culprit is your OS/game, not rollover:
For the specific combo W + LAlt + Space, the most common culprit is your OS/game, not rollover:
- On Windows, Alt + Space is a system shortcut (opens the window/system menu). Some games still get weird with it (especially windowed/borderless), which can prevent the Space press from reaching the game while Alt is held.
- Test the combo on a key rollover tester while holding W + LAlt + Space to see if all 3 are detected.
- Try swapping LAlt to RAlt, or bind “run” to Shift/Ctrl temporarily and see if the issue disappears.
- If you’re on Windows, try true fullscreen vs borderless windowed and retest.
