BEGIN RANT Good luck. Other keys could be used by assigning them as accelerators to an ixMenu (see below), but beware that new versions of NewEra (I'm running 3.10.TC1) are flaky in the area of trapping combinations of Return (Return, Ctrl+Return, Alt+Return, etc.). In the good old days, you could trap Return with accelerator Ctrl+M, but that went away recently. Ctrl+Return is the same at Ctrl+J (I think; I'm going from vague memory now, but the point is the same - certain Return combinations relate to certain Ctrl+alpha combinations and some don't), but it's changed in bug fix releases & etc. so often that I'm not sure what expected behavior is anymore. There's a feature request (submitted by me) to allow ANY ASCII value to become an accelerator; which means we could assign ASCII 13 (RETURN) to an accelerator and do tons of nifty things (including shooting ourselves in the foot). Or you could trap and disallow the use of the letter "w" anywhere in your application (which I support; any letter whose name has more than one syllable should be eliminated). END RANT You could, however, assign some other accelerator key: e.g. Two Radio buttons rbOne and rbTwo. Title them with underscores to visually cue the user that hot keys are assigned ("&One" and "&Two"). create a couple ixMenus with Alt+O Alt+T as accelerators. The activate() events of the ixMenus call a function, sending "O" and "T" respectively. ... IF param = "O" THEN LET myRadioButton = self.rbOne ELSE LET myRadioButton = self.rbTwo END IF -- make sure you check isEnabled(), since the accelerator ignores the state of the ixMenu or the control we're -- working with by default. IF myRadioButton.isEnabled() THEN CALL myRadioButton.push() END IF I hope you get the idea, or at least you're sorry you asked. -- //////////////// ======================================================= ////////// // Dennis J.
