Description arne anka CLA 2005-01-25 07:50:22 EST 
type a new line of text, insert linebreak by pressing enter and the ctrl+z ... the newly line of text is gone. i 
expect ctrl+z only to undo the linebreak not the whole newtyped line.
this is especially annoying in conjunction with autocompletion: sometimes, don't understand why, after 
the list of suggestions pops up the whole editor moves a few pixels down, just the moment i pressed 
enter to choose. thus i get an incomplete stub and a linebreak ... undoing the linebreak results in the 
above.
see this on solaris 8 with kde2 and linux 2.6 with kde3 -- so i assume it's a problem on all platforms.
if it matters: happens when coding java.

if this is the wrong category: the interface is somewhat unclear and confusing -- im not able to determine 
what all this categories mean.

This is as designed. Undo is not line based i.e. if you type some text with
several newlines it will remove all together.

of course is undo not linebased and i don't expect it to.
but undo should be _action_ based! typing text and pressing enter are two different actions which 
should be undoable one by one.
i'll watch 49553.
