Changes to "Measure operations" in the Handbook (svn2690)

The procedure given in the handbook included in svn 2690 for deleting measures doesn't seem to work as it appears to have changed.

I would like to suggest the following alterations to the "Delete" subentry with additions in the "Append" and "Insert" subentries to add the keyboard shortcuts for multiple appends and insertions.

I haven't been able to insert the Mac clover leaf glyph nor the right arrows of the original...

I have copied the existing text when unmodified and encapsulated my suggestion in <newtext> tags.

Measure operations
Append

To add a measure to the end of the piece press Ctrl+B (Mac: <cloverleaf>+B>. To add multiple measures use the menu Create > Measures > Append Measures <newtext>or press Ctrl+Shift+B (Mac:???) and enter the number of measures you wish to append in the box that appears.</newtext>

Insert

First select a measure then press Ins to insert a new empty measure before the selected one. To insert multiple measures use the menu Create > Measures > Insert Measures <newtext>or Ctrl+Ins</newtext>.

Delete

To delete a measure you have first to select it in a special way. Press Ctrl (Mac: <clover leaf>) on the keyboard as you click on an empty part of the measure with the mouse. The measure is marked with a blue rectangle to show you have selected a "piece of time". <newtext>Press Ctrl+Shift (Mac: ???) while clicking on another measure to extend the selection. Pressing Ctrl+Del removes the selected measure or measures.</newtext>
