Rename clips on several tracks

You can use the following script to rename a clip without any mouse clicking - in this example it renames the clip and suffixes the name with some text:

function renameClip(callback) {
    //Make sure Pro Tools Edit Window is active
    sf.ui.proTools.appActivateMainWindow();

    //Make sure we have no search in Clips list - if we had, Clip Rename won't work (Pro Tools bug)
    sf.keyboard.press({ keys: 'cmd+shift+d' });

    //Clip Clip->Rename...
    sf.ui.proTools.menuClick({ menuPath: ['Clip', 'Rename...'] });

    //Wait for 'Name' dialog to come up, assign the dialog to dlg variable
    var dlg = sf.ui.proTools.windows.whoseTitle.is('Name').first.elementWaitFor({}, 'Could not find "Name" dialog').element;

    //Find the first text field
    var textField = dlg.groups.whoseTitle.is('Name').first.textFields.first;

    //Get the current Name
    var currentName = textField.value.value;

    //Make a variable with the new name, based on the old one by calling the callback function provided in the 1st argument
    var newName = callback(currentName);

    //Set the value of the textField
    textField.elementSetTextFieldWithAreaValue({ value: newName });

    //Press OK
    dlg.buttons.whoseTitle.is('OK').first.elementClick();

    //Wait for the dialog to close
    dlg.elementWaitFor({ waitForNoElement: true });
}

renameClip(function(oldName) {
    //Make the new name the oldName plus ' PREF'
    return oldName + ' PREF';
});

And this script could help you navigate exactly two tracks up.

function trackGotoDelta(delta) {
    let visibleTrackNames = sf.ui.proTools.visibleTrackNames;
    let selectedTrackName = sf.ui.proTools.selectedTrackNames[0];
    let visibleTrackIndex = visibleTrackNames.findIndex(n => n === selectedTrackName);

    let newVisibleTrackIndex = visibleTrackIndex + delta;
    let newTrackName = visibleTrackNames[newVisibleTrackIndex];

    sf.ui.proTools.trackSelectByName({ names: [newTrackName] });
}

trackGotoDelta(-2);

Those could be easily combined - depending on how exactly you need it to rename, and if in fact it always needs to go 2 tracks up, or if you need it to navigate to a track by name.
The more details you give, the easier it will be to help you get the best possible version of the script.
