My Custom Stopwatch App - Questions on LONG KeyPress & triangle charmap

Hi - I'm making my own (VERY simple) customised stopwatch app (for me to track Sets and RestTime)
Couple of questions.

1) http://developer.garmin.com/downloads/connect-iq/monkey-c/doc/Toybox/WatchUi.html
based on the above link - how does one get a LONG Press of a key? eg: I want to do a Reset of the timer (the native timer does a LONG keypress of the DN key)

2) in the native timer, there is a little triangle beside the Reset word, how do I get this little triangle?


Thanks
