Here's an updated version of the plugin which supports more keys in the DxInput.Type action.

Here's the info from actions.xml:

QuoteTypes <Text>.  You can enter a sequence of keys or a string.  You can use any letter number or the following punctuation:    [ ] , . / ? ! @ # $ % ^ & * ( ) _ + ' "
Other keys can be specified by using {} such as {tab} but you can't do key combinations.
Some special characters may not work depending on you keyboard language.

Example parameter:   Hello There.{return}{tab}Good? Yes!{return}

This version of the plugin will be included in VC 0.940 when I release it.

Is it possible to add mouse cursor movement to the plugin?

I don't think so.

Did you try the standard Mouse.* actions in VC?

unfortunately, this action does not work where DirectInput is required (in 3D games), for example, to rotate the camera, etc.
