> Do not create undoable commands everytime we type a separator. Having this, we can do in-place find/replace of sequences with whitespace again such as selecting "first" and replacing it with "at: 1" followed by hitting CTRL+J or CTRL+SHIFT+J to do the replacement again. > > Note that commands will still end if the user changes the selection by, for example, moving the text cursor. Or when deleting things via backspace. Or when inserting stuff from the clipboard, or This is an improvement, thanks, but one thing I don't understand is why this function is tied to the unit-of-Undo..? Because, in the old S&R all of the above used to work. Replacing a selection with [Backspace] is how I handle S&R's in which I need to simply remove chunks of text. Also, sometimes the replacement text is a complex String that is very onerous to type, so pasting from the clipboard must work too. One more case, in the old S&R, one could be typing the replacement text and, if a typo occurred, no problem! Backspace, correct, keep typing, and the system was amazingly smart enough to do it right. I don't know how it did it but it was brilliant.. > ... just look for senders of #closeTypeIn or #insertAndCloseTypeIn to get the idea.

Agree. I just checked the server, all looks fine except it did copy this version to the historical repository. Just to be safe, I moved the files to the /treated. Karl, would you mind reverting to the ancestor (ar.4662) and then re-committing it as 4712? Please don't reuse 4711 again. Thanks.
