AutoHotkey Community

I tried to accelerate the auto-replace code writing.
For that purpose I wrote the following code:
::ar::
Send, {Home}
Send ::^{Right}{BS}::{Home}{Right}
Return

UNFORTUNATELY, the {Home} command does not move cursor to the beginning of the line within SciTE4AutoHotkey. But, it moves it in Notepad.
So, to walk around the problem, I had to change my code to:
::ar::
Send, +{Home}
Send, {Left}
Send ::^{Right}{BS}::{Home}{Right}
Return

Now (as an example), let's imagine you type in SciTE4AutoHotkey
rel relativity ar (and press Space)
YOU WILL GET:
::rel::relativity
(And, your cursor will be in the position to add the suitable auto-replace option. This code accelerates the process of adding new hotstrings.)

QUESTION: Why the {Home} command does not move cursor to the beginning of the line within SciTE4AutoHotkey?
Is it a bug?
Or, Am I doing something wrong here?

Have you tried do it with actual key pressed with your fingers on your keyboard? You will see that autocomplete gets activated as you type "ar" (it suggests "Array" and other things), and the pressing Home goes to the first command in the autocomplete list. So perhaps instead of "ar" try a letter combination that doesn't occur anywhere else, like "aqq".
