Working on selections

It is possible to mark a range of expressions. You can then modify one or more properties from the selection or save them as a new file.

If you keep the Ctrl key pressed while clicking on an entry, the whole row is marked for further processing. A click on a marked entry will remove this selection.

When you additionally press a Shift key when clicking on an entry, the selection will be extended from the current entry to the point where the cursor was previously.

You invoke the edit dialog to modify the selection by pressing Return. In this case the dialog appears differently. Some properties are disabled. For example it does not make sense to edit the expression itself or the remark of a whole range.

All selectable fields are empty at the beginning to represent the unmodified state. Once you have modified a property there will be contents in its field and only those properties are altered in your selection when you confirm the dialog.
