Navigate to a Tcl element's declaration

In this section you will learn how to easily find a "declaration" of a referenced Tcl variable (usually, a set command for the variable).

  1. Create a new project as shown in the first secion o this tutorial.

  2. Create a new Tcl file within that project. Then copy and paste the following code:
    set var 1
    proc modify {arg} {
    set b 0
    puts "before: $arg"
    set arg $b
    puts "after: $arg"
    }
    modify $var

  3. Set cursor to the $var variable reference at the last line.

  4. Select Navigate > Open declaration menu item.

    Declaration

    Now the declaration of the variable is selected in the editor.
    Note that you might also use F3 key or left click the variable reference holding Ctrl key instead of the using menu item to achieve the same effect.

You can navigate to the Tcl procedure declaration the same way.
