Hex Editor Neo offers the unique feature called multiple selection. Unlike in most other editors, where you are only allowed to select a contiguous text or data, Hex Editor Neo allows you to have several contiguous ranges (or blocks) in a selection. In addition, you are not limited in a number of such contiguous blocks, there can be as many blocks as you need.
By default, the multiple selection feature is enabled. When you start selecting data, all previously selected data remains selected.
Most Hex Editor Neo commands work with a current selection. Among those commands are:
This option, being enabled, makes Hex Editor Neo always drop current selection before selecting new block. You can still take advantage of the multiple selection using mouse.
