Editing In Selection Areas
Editing can be restricted to the current selection area. This allows the user to "Lock" the alignment either side of the selection area. Any gap insertions or deletions will only affect the current selection area.
In this example, if Sequence IL2RA_MACMU has gaps removed from position 98-104, the same number of gaps will be inserted at position 116, (between M and L).
Locked selection area based editing was introduced in Jalview 2.08
