[HotKeyNet] Sending keystrokes from slave to master?

[Freddie]

I understand how it works.

I don't understand why World of Warcraft can still receive hotkeys from the Slave,

Probably because you're using SendWinM or SendWinS in those hotkeys. Those send modes don't generate keyboard events. Those send modes communicate directly with the WoW client and tell WoW that a keyboard event occurred even though it didn't really. Input Director has no way to know that HotkeyNet is sending those messages to WoW.

Unfortunately, those send modes probably won't work with Vent because Vent is intercepting keystrokes on a system wide basis, which means it's probably receiving its keyboard input with either a low-level keyboard hook (see my last post about launch order) or else it's using an operating system registered hotkey.

Does Mojo have the ability to create hotkeys that can be held down and sent to any system?

The old Mojo never got beyond its first two months of development. It's just a bare bones KM program. It has a really nice hotkey entry window (one of the best pieces of programming I ever did in my 30 year programming career) but it can't do what you describe.
