Easy trick to keep any combination of keys held down without manual effort.
- Step 1: Hold down desired keys (Usually M, sometimes C, E, and/or R).
- Step 2: While holding desired keys down, click on another tab to unfocus Antimatter Dimensions.
- Step 3: Let go of desired keys.
- Step 4: Click back on Antimatter Dimensions to bring it back in focus.
- Step 5: Profit.
The only con is that this breaks when you tab out of AD.
Exception being R, which continues to work until R is pressed again.
