Send Ctrl + + (Ctrl+Plus) to a Windows application

Question

I have a Windows desktop application where I want to press Ctrl + + with AutoIt, it should open a new window (or increase font size in Chrome/Firefox/etc). I don't know why but it doesn't work.

I tried it with Send() in several ways without success.

My latest .au3 code:

Local $hWnd = "[REGEXPTITLE:(?i)(.*App Window Title*.)]"
WinActivate($hWnd) ; WinActivate finds the window and activates it
Sleep(500)
Send("{CTRLDOWN}{+}")
Send("{CTRLUP}")

Previous attempts:

Send("^{+}") based on documentation, nothing happens

Send("{LCTRL}{+}") it writes a plus sign to the active input field

Send("^{ASC 043}") it writes a plus sign to the active input field

Send("{CTRLDOWN}")
Sleep(500) ; with and without sleep
Send("{+}")
Send("{CTRLUP}")

When I tried Send("^p") in Chrome it opened the print preview window (Ctrl+P).

Answer 1

The solution is: Send("^{NUMPADADD}") or Send("^{NUMPADMULT}")

In Chrome only the NUMPADADD works.
