On a Windows machine, clicking and holding a keyboard key results in the key being types multiple times. For example, if I click and hold 'q' for a few seconds, I end up with the following:

qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq

Similarly, I can click and hold the Backspace key to delete multiple characters. On a Mac, it seems, clicking and holding a key for several seconds results in the key being types only once. To type it repeatedly, it is necessary to psychically click it multiple times.

I'm unclear about whether that is a bug or a supposed-feature, but I am interested in replicating this functionality on a Mac.

Any ideas?

Thanks!
