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.
