Are you asking about the
"tap" output function, where you release a sip/puff input quickly and it activates the output?
"the same button" Are you referring to a switch input or does "button" refer to a controller button output on an emulated game controller?
I can interpret your question several ways. You mention "PC with keyboard", but they can also use game controllers. Does "button" refer to a keyboard key?
A specific output, either a controller button or a keyboard key, can be used on multiple rows in a configuration spreadsheet to be controlled by more than one input. In general the different rows do not interfere with each other, but there can be some interactions if using greater_than or less_than output functions, or latches, like toggle or delayed_latch.
Share any spreadsheet you are asking about.
