[Newbies] Using text morph to save characters

[Bert Freudenberg]

The new characters are inserted before the current cursor position. So if the cursor is "1" then the new characters are inserted before the text. Now if the cursor is the same as the count of characters, they are inserted before the last character. You can verify that by "clearing" the Text to e.g. "X".

I'm not really sure what the rationale for this behavior is. I was surprised. Asking on the Squeakland list is a good idea for Etoys issues like this.

Likewise, if I initially generate two b(s) in a row, and then an a, the a gets inserted between the two b(s), not at either end of the string, as would be expected.
