winactivate | Easy-to-use Windows HWID/KMS38 Activation Script

Maybe WinMaximize could help you

There are some things you can do to make sure that your script runs correct. Is your PureRef window really activating with ahk_class Qt5QWindowIcon?

The standard variable %clipboard% contains the clipboard as text.
You could also try SendInput, SendRaw and SendPlay to send the clipboard as text.

The most appropriate way to activate a specific window and send keystrokes to it is as follows:

Here is the method I typically use to detect empty variables

Code:

When you're using a ternary, you're in an expression.

Legacy commands can only be used when in a legacy statement, so more clearly said, only at the start of a new line _{^{(under normal circumstances)}}.

What you're trying to do right now, is concatenate three variables together _{^{(and discard the result)}} named WinActivate, ahk_class and a dynamic variable named PrevActiveClass.

how to implement the same logic in one line of code?

You can't.

The best you can do is two lines:

Solution:

It's because the window that appears, doesn't come from the git-bash.exe process.
It comes from mintty.exe, which gets launched somewhere down the line after you run git-bash.exe.

Most simple thing you can do, is wait for the window to appear after launching git-bash.exe, like so:

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

In Chrome only the NUMPADADD works.

Seems like a pretty questionable approach.
I would rather see about somehow setting this to be the default behavior, or automating this with COM instead of sending a hotkey.
Anyway, for the hotkey approach, this seems to do the trick:
