STEPS TO REPRODUCE 1. reply to a message 2. in composer window put your cursor in the somewhere on any text line (except the first character of that line) 3. type ctrl-k (the shortcut for Delete line) OBSERVED RESULT the current line is deleted from the cursor position until the end of the line EXPECTED RESULT the entire line is deleted, regardless of where your cursor is positioned ADDITIONAL INFORMATION this is how Kate works and it would be nice to have consistency from my Emacs days I do like "delete from point to end-of-line" but that's not the same as "Delete line"
So at the moment it's more as "from my Emacs days I do like "delete from point to end-of-line" but that's not the same as "Delete line"" :) Ok indeed it can be better to delete all lines I will fix it
