in reply to Trying to capture Alt characer in Perl

Strictly speaking, there is no <Alt> character per se, the <Alt> and indeed <Ctrl>, keys are modifiers in as much as the actual character typed is modified to a different ASCII value, so you should refer to the wisdom forwarded by other monks WRT establishing the actual data values that the <Alt> & <Ctrl> keys generate.

A user level that continues to overstate my experience :-))
