The PercTint startup switch defines the amount of shading applied to the window behind the currently displayed window to help draw attention to the current window (when using a border style other than the Modern border style which applies shading automatically). Setting PercTint to 100 applies no shading. Setting it to less than 100 darkens the background. Setting it to greater than 100 lightens the background.
Usage:
PercTint= [###] where ### is a three digit number.
Example: Keystroke.exe PercTint=150
Default:
100
PercTint is commonly used with TintColor to control shading.
Note: The forward slash (/) is not used with this start up switch.
