Insufficient space in track - for pasting audio or restoring cut audio

These two errors only occur if you make non-default settings in Tracks Behaviors preferences.

Both of them require you to have turned "off" the setting for "Editing a clip can move other clips" by un-checking it.

The default setting for this is "on" and in that case any following clips are moved to provide room

There is not enough room available to paste the selection

If there is sufficient room to paste the selection that you placed on the Audacity clipboard with Cut or Copy without moving the succeeding clips then the Paste will take place.

If there is insufficient space then this error message will be shown and the clipboard contents will not be pasted.

You may want to turn back "on" the setting for "Editing a clip can move other clips" by re-checking it in Tracks behaviors preferences.

There is not enough room available to expand the cut line

If you have turned "on" "Enable cut lines" in Tracks behaviors preferences you can then click on the cut line at any time to restore the cut audio.

If there is insufficient room to restore the cut audio without moving succeeding clips the this error will be shown and the cut audio will not be restored.
