(Pro Tools) Code to apply macros to only highlighted track?

Hey @Owen_Granich_Young ,
You script is good but I believe Matt wants to tab to each transient and paste for drum replacement. Your script replaces clips.

This script will tab to transients and paste a sample to a destination track until it reaches the end of the audio in the source track

function checkForSingleTrack(selectedTrack, sourceOrDest) {
    while (selectedTrack.length != 1) {
        alert(`Only one track can be used as a ${sourceOrDest} track. Please select one track and click OK`);
        selectedTrack = sf.ui.proTools.selectedTrackNames
    }
}

const tabToNextTransient = () => sf.keyboard.press({ keys: "tab" });

sf.ui.proTools.appActivateMainWindow();
sf.ui.proTools.mainWindow.invalidate();

//Get Original Selection and tracks
const originalSelection = sf.ui.proTools.selectionGetInSamples();
const originallySelectedTracks = sf.ui.proTools.selectedTrackNames;

//Instruct user to select source and destination tracks
sf.interaction.displayDialog({
    title: "Select Source",
    prompt: `Before proceeding be sure to have copied your
sample into the clipboard. Then select source
track and click OK.

Source track should be consolidated or else
samples will be placed at clip boundaries.

(You can copy sample and  consolidate 
before clicking OK)`,
    buttons: ["Cancel", "OK"],
    defaultButton: "OK"
});

var sourceTrack = sf.ui.proTools.selectedTrackNames;

// Verify that a single source track has been selected
checkForSingleTrack(sourceTrack, "source")

// Have user select destination track
sf.interaction.displayDialog({
    title: "Destination Track",
    prompt: `Select destination track and hit OK.
(Click on track title, not in the editor)`
})

var destinationTrack = sf.ui.proTools.selectedTrackNames;

// // Verify that a single destination track has been selected

    if (destinationTrack[0] == sourceTrack[0] || destinationTrack.length != 1) {
        let answer = sf.interaction.displayDialog({
            prompt: `You have either selected the same track for
source and destination or have selected more
than one destination track.

If you are pasting to multiple tracks then the
samples in your clipboard must match the
number of tracks, track width, and track order
you are pasting to - proceed with caution.

If needed, reselect destinations tracks.
