Is it possible to "Freeze" track at top?

In Excel spreadsheets, I can “freeze” the top spreadsheet row and scroll below, so the top row stays in view at all times. In Audacity, if I have a click track as my top track and a label track with measure #'s, is there a way to freeze those tracks and be able to scroll up and down into the lower tracks?

No there isn’t, but you can drag tracks up / down to a convenient position, and you can also “collapse” tracks so that you can fit more tracks on the screen.
To drag tracks up / down, click on an empty part of the info panel on the left, and drag.
To collapse / expand tracks, click on the button at the bottom of the track info panel (http://manual.audacityteam.org/man/audio_tracks.html#collapse)
