Any reason you dont want to use Amiga OSes inbuilt copy& paste ? (Ramiga + x/c/v)
That doesn't work everywhere. With those external programs you can try to copy text from anywhere even when it's not highlightable/selectable.
And pasting works too even when program doesn't support clipboard pasting. For example PowerSnap can paste placing character by character into input stream. That has been very handy for example with telnet programs which don't support normal paste.
