Set Variable to Text Action

The Set Variable to Text action allows you to set a selected variable to plain text, by either typing in the text box, or selecting a Token.

Examples

Set To Text You Type

Set to The Clipboard

Set To Another Variable

See below for how to use dynamic variable names.

Combine Multiple Variables and Text

There is no need to use any operators when combining text with multiple variables or other tokens. Just enter the text and variables/tokens as you would like them to appear in the Variable being set by this Action.

Setup

Configure the Action as Needed

  • Select the variable to set from the Set variable pop-up or enter a variable name.
  • In the text area, Enter the text and/or Tokens (which include Variables).
    • You may intermix text and tokens as much as you like
    • You can type the Token, in the format of %TokenName%, or select it from the popup list under Insert Token.
    • Tokens include variables, calculations, clipboards and more.
    • You can create a dynamic variable name using this format: %Variable%%%Variable%myVar%%%

Unlike most places you specify a variable, the variable name itself is a text token field, so you can set a variable whose name changes.

The Set Variable to Text action allows you to control what text processing happens in the gear menu (7+) :

  • Process Text Normally (process text tokens and backslash characters)
  • Process Text Tokens Only (process text tokens but not backslash characters)
  • Process Nothing (process neither text tokens nor backslash characters)

Most other Text Fields in Keyboard Maestro process both text tokens and (except for regular expression fields) backslash characters.

Tip: leave notes for yourself about what you're doing. Click on the gear icon at top right of the action to select Set Note…. A window appears where you can enter text. Click the OK button to save the text of the note for future reference.

How To Use Dynamic Variable Names

In some languages, this is known as indirection, where one variable is really referring to another variable. This is a bit complicated, and you may not often need it, but it is very useful when you do need it.

Dynamic Determination of Variable Name in Text Area Block

This requires two steps (two Actions):

The Steps Are

  • STEP 1.
    Set Variable to Text Action (this action) to dynamically determine a standard variable token based on one or more variables, which optional text.
    • In the text area of the Action, enter a special form of the Token entity, where you will embed another Variable token, and optionally text.
    • For example: %%Variable%%myVar%Variable%myVarNum%%%
      • Note the use of two percent symbols (%%) in places where you want the result to be one %.
      • Here is how this text will be processed when the Action executes:
        .
        %%Variable%%myVar%Variable%myVarNum%%%
        
        TEXT                  BECOMES
        %%                    %
        Variable              Variable
        %%                    %
        myVar                 myVar
        %Variable%myVarNum%   2
        %%                    %
        
        RESULT WHEN EXECUTED
        %Variable%myVar2%
    • This is the variable we want to get the results of, so we will need another Action to get it.
        
  • STEP 2.
    Filter Action using the Process Tokens option.

Dynamic Determination in Variable Name Block

Since the Variable Name block of the Set Variable to Text Action accepts tokens, we can just use it directly if we just need to concatenate two more more Variables, with optional text.

  • For example: %Variable%myPrefix%%Variable%myFieldName%
  • When this action executes, it will first evaluate these tokens to produce something like: myAddress, and then set that Variable to the results in the Text Area block.
