Novice on AHK here. Here are the lines:
^Alt:: Send, b ^!PGDN:: Send, r
The "^!" part of the second line gets send continuously before PGDN is pressed, and I get something like "bbbr", so I have tried:
Alt & AppsKey: return ^!PGDN:: Send, r ^Alt Up:: Send, b
^!PGN:: works normally, but when
^Alt Up is released, it fires, so I get "rb".
To clarify, I want just r, or just b, not a bundle.
Also, I plan to use other combinations of the type, with one line consisting of two modifiers and the other consisting of the same two modifiers and a normal key, so the solution cannot prevent further cases such as this one.
