When analyzing one of your custom scripts, I was curious as to the origin of the numeric values passed to .IsKeyDown() after noticing they weren't my typical ASCII values.

I found a few key code sites, like https://www.foreui.com/articles/Key_Code_Table.htm. Is there another standard chart you use?

You don't really have to worry about that if you use their editor. It will ask you what keys you want when you auto-complete the method name.

If you want to do things the hard way, you can consult this chart: https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.keys

I prefer easy, but my version does not show that after typing. I do not have the Steam version, though.
I'm a developer, too, so don't mind getting my hands dirty in code, though.....

UPDATE: The editor popup in the graphic you sent does not invoke by just typing, ; however, it will show if I double-click the method name in the intelisense dropdown with my mouse.

More or less how it was invoked for me was that I typed the first few letters of the method name... used arrow keys to select the correct one and hit Enter. I didn't need to use my mouse.

Tried that, too. The double-click seems to be the most consistant on this system, though. Who knows?
