When keying in functions with multiple parentheses I often type, for example,
strip() then backspace and enter the argument.
If I do this using right-key-Morph in a datasheet, and hit Return while the cursor is inside the parentheses, the right hand parenthesis disappears. If I then restore the parenthesis and hit return, nothing happens. If I hit the Morph button, the field clears completely.
What's actually happening is that the right parenthesis isn't removed, it's rendered invisible! If I ignore its apparent disappearance the morph works fine.
But I still can't get the Return key to trigger the Morph operation with a strip( function entered.
Maybe my entry mode is odd but it works for me and I don't lose track of parentheses. And there is something odd happening here - on both my Macs.
