Hi,
is there a system-portable way to determine if a given key is pressed?
I found this:
https://ch.mathworks.com/matlabcentral/fileexchange/64380-determine-whether-a-key-is-up-or-down
but it only works for windows....
cheers,
Daniel

Depends what you mean and what you are willing to live with.
For regular keys and you are willing to have a figure covering the display then WindowKeyPressFcn callback and test the event structure.
If you need the check to work without a figure then see:

There might also be Java approaches.
The psychtoolbox functions are more complete and robust and better suited for timing.
