Maybe you did not fully understand what the MainUnit directive does.
It allows you to jump between the Pascal unit and the include file in
any situation, just as if they were one single file.
It works also if you opened first an include file from a search window.
The other way around (unit -> include file) it works even without a
MainUnit directive.
Thus, Lazarus editor fully understands include files unlike Delphi' editor.

In other words you can always do Ctrl-Shift-Up in a method / function
and it does the right thing.
You don't need to worry about if your cursor is on a unit or include
file source.
