Screenkey.ahk is a tool that displays the keys that you type on the screen. It can be useful for screencasts or remote help.
You can run it as an Autohotkey script or run the compiled exe directly.
There are a few customization options that can be tweaked at the top of the script:
Font settings:
fontSize = 20
fontName = Verdana
fontStyle = Bold
Maximum number of keys that can be displayed on the screen at any time:
numButtons := 5
Gui transparency:
transparent := true
Distance from the buttons to the edge of the window
winMargin := 25
Speed typing settings:
useSpeedTimer := true
speedTimer := 1000
When useSpeedTimer is true, previous keys will be cleared when typing new keys after the specified interval (speedTimer)
This is handy when trying to show key combos.
