1. Go to 'Grid' and find the reservation you want to make changes to.
2. If you put the cursor on the reservation and right click and hold you can drag the reservation to another room or date.
If you put the cursor at the edges of the reservation you can drag the edges to extend or shorten the stay.
3. When you have made a change a panel showing the changes will appear to the left. If you press 'Clear' button in the panel all changes will be removed.
4. The left panel will display a summary of the changes you are about to make, note that there can be a rate change due to your change (if you have changed the date for example). If you don't want the rate change you can enter the reservation and change it back after the changes or you can use 'date and/or room change' function in the reservation instead. Click 'Save' button to make the change.
