Full measure rest

When an entire measure is devoid of notes, a full measure (full bar) rest is used.
A full measure rest looks like a whole note (semi-breve) rest, except it is centered in the middle of a measure

To create a full measure rest, select a measure and press Del. All notes and rests in this measure are then replaced by a full measure rest.

Multi-measure rest

Multi-measure (multi-bar) rests indicate a long duration of silence for an instrument and are frequently used in ensemble sheet music. They are automatically interrupted at important points, such as double bar lines, rehearsal marks, key- or time signatures, etc.
Multi-measure rests have a number above the staff indicating the duration of the rest by the number of measures

Instructions

1. From the menu, choose Style → General...
2. Click on the "Score" tab, if it is not already selected
3. Add a check mark next to "Create multi-measure rests"

Limitations

The style option automatically creates multi-measure rests throughout the score. Therefore, it is recommended that you enter all your notes first and then turn on multi-measure rests afterward.

You may want to have a multi-measure rest divided into two multi-measure rests.

This option should be checked before turning on the "Create multi-measure rests" option in Style → General..., in the "Score" tab.
Select the first measure where you want the second multi-measure rest to start, and do a right-click Measure Properties → Break multi-measure rest.

Note that multi-measure rests are interrupted if there is a rehearsal mark (not a simple text), section break, key or time signature change, or double bar line.
