No, you can't right now. But it is a planned feature.  (input="-")

This would have the advantage of bypassing any LFS problems. (?)
The only (minor) problem I see is that data taken from stdin would
obviously have to bypass the G_percent() calls (that's ok) but as a
replacement I'd like to use G_clicker(), and I'm not sure how well the
GUI version will deal with that. (would need some help from a Tcl expert)
