How determine if a key is pressed

Hi,

is there a system-portable way to determine if a given key is pressed?

I found this:

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.
