The IDE provides a feature which allows to set a bookmark at the current cursor position. Later, the cursor can be returned to this position by pressing a keyboard shortcut.
Up to 9 bookmarks per source file can be set up, they are set by Ctrl-K <Number> (where number is the number of the mark). To go to a previously set bookmark, press Ctrl-Q <Number>.
Remark: Currently, the bookmarks are not stored if the IDE is left. This may change in future implementations of the IDE.
