Razor Eraser - Hold Key + Right-Drag to Delete Areas

A temporary “eraser” mode — while you hold its shortcut key, right-drag to directly delete the swept area. Under the hood it borrows REAPER’s Razor Edit to select and delete the area. Two variants, differing only in whether the deletion area snaps.


Two Variants at a Glance

Exact Action List display nameDoes the right-drag selection snap?
Razor eraser (hold key + right-drag to delete areas)Snaps to grid / Item edges and other snap points
Razor eraser ignoring snap (hold key + right-drag to delete areas)No snapping; placement follows the cursor exactly

How to Use

  1. Assign a shortcut key to this Action.
  2. Hold that shortcut key.
  3. Right-drag in the Arrange view to frame the area to delete.
  4. Release right-click → the framed area is immediately deleted.
  5. To erase another area, right-drag again.
  6. Release the shortcut key → exit eraser mode.

Think of it as “hold key = pick up eraser, release key = put down eraser”.


Common Behavior Details

  • Entering eraser mode clears any existing Razor selection first, to avoid accidental deletion on entry.
  • Deletion uses REAPER’s standard “Delete razor area” behavior: deletes Item contents and clears the selected area.
  • Each right-click release is one Undo — if you erase wrong, press Ctrl+Z once to revert that stroke.
  • On exit, any remaining Razor selection is cleared and the right-click modifier settings are restored to your original configuration (the eraser temporarily borrowed right-click; it is returned on exit).
  • While the mode is active, right-click is temporarily occupied for drawing deletion areas; the normal right-click menu is suppressed.
  • A small hint text follows the cursor telling you that you are in eraser mode.

The Only Difference Between the Two Variants

The only difference is whether the right-drag selection snaps:

  • Razor eraser (snap version): the selection snaps to grid / Item edges and other snap points.
  • Razor eraser ignoring snap (no-snap version): the selection does not snap; placement follows the cursor exactly.

All other behavior (clear old selection on entry, each right-release = one Undo, clear remaining selection and restore right-click settings on exit, cursor hint text) is identical between the two.

When to Use the No-Snap Variant

  • When the area to delete is not on a grid / Item boundary and snapping keeps pulling you off target.
  • When you want to freely scrape off a small segment without snap interference.
