Define Abbreviations in the first column that when used in a parameter expression will expand to the string defined in the Expands column. Forget absTime.seconds, use #AT! With Replace inline enabled on the component (off by default -- without it an abbreviation only expands when it is the entire expression) the abbreviations work in-line too, meaning you can type #AT * 0.2 or even combine them!

Most of the behaviors below live behind their own toggle on the component, and only CustomPar Promote Enable is on by default: #@op Wrap Enable gates #@, #! Parent Shortcut Enable gates #!/#!!.

There is a special reserved abbreviation, #@ which will wrap anything valid after it in op('...'). So #@noise1.par.amp becomes op('noise1').par.amp saving you some heavy keystrokes!

Another special abbreviation #! will resolve to the closest parent shortcut, as well as #!! will also add a .par after it!

  • #!.par.Something -> parent.Project.par.Something (for example)
  • #!!Something -> parent.Project.par.Something (for example)
  • Encouraging even more to use parent shortcuts (which you can easily add by ctrl+shift-clicking on the diamond button

Two more abbreviations promote the parameter you're typing in straight to its parent (via CustomParTools, if installed) and replace themselves with the resulting shortcut path:

  • #@! promotes with a Bind reference
  • #@~ promotes with an Expression reference
  • Leave off a name to reuse the parameter's own name, or supply one, e.g. #@!MyName

IMPORTANT: due to what's available through the TD API, you need to have your mouse over the parameter box when finishing typing (either by clicking away, in which case you need to move the mouse over to the parameter again, or my suggested way of hitting Enter).
