I've an unexpected behavior by selections in SciTE.
The following script causes, the word under the cursor is selected. This can either apply to the Word character (by pressing Ctrl + Shift + E) or additionally with leading "$" for variables (by pressing Ctrl + E).
This works perfectly - as long as the right of the term is a space. If this is not so, then ranges are selected that do not correspond to the markers. Incidentally, it does not matter how I run the selection ( Selection Start / Stop; SetSel (); CharRightExtend () ), always the same behavior.
Any Ideas..
Edit: Have found the failure - by default use SciTe "Ctrl+E" to match next brace. No i've changed the hotkey and it works like expected.
