Keywords

You can assign a keyword to a button.

In Lightroom

Go to Files→Plugin Extras→MIDI2LR Keywords. MIDI2LR starts indexing your keywords as soon as Lightroom is started. If you have thousands of keywords, it may take a minute or two. If you open this menu before it is all indexed, you'll get a message telling you how many keywords have been indexed so far, and you'll then receive a bezel notification when the keyword indexing is completed.

In the keywords dialog you can assign a keyword to Keyword 1 through Keyword 64. This corresponds to the button commands you can assign in the app. For each that you want to assign, select the desired keyword. Your changes will only be saved once you press the OK button. The next time you open this dialog, the selected keyword is highlighted. Note that the highlighted keyword may not be immediately visible. Scroll down the selection box and you will see your highlighted keyword.

In the app

The mapping pop-up for the app shows a category Keywords just below Develop presets. Assign the desired Keyword number to the button. Remember to save your new mapping using the Save button on the app.
