Hello Folks! Some more questions about GRX in its GNU Pascal interface... AFAIK, every keyboard event in GRX is a single constant like e.g. GrKey_A for keys 'SHIFT' + 'a' GrKey_small_a for key 'a' without modifiers GrKey_Alt_A for keys 'ALT' + 'a' etc. Question: Is there an easy way to split a keyboard event into single key "events"? E.g. GrKey_A = GrKey_small_a + GR_KB_SHIFT GrKey_Alt_A = GrKey_small_a + GR_KB_ALT etc.? Yours Markus P.S.: Maurice, thanks again for your hints concerning "GrKeyRead vs. readln"!
