3-clicking a non-directory searches for matching text in the body of the corresponding Sheet (or if in a Col background, just in the textbox itself). All matches are highlighted, but the cursor remains on the clicked match. On subsequent clicks, the cursor jumps to the next match. (This slightly deviates from Acme, which jumps to the next match even on the first click.)
