The help text for the command line qualifier -select twice erroneously uses -goto instead of -select. See boldface text in excerpt below.
Making Selections
Selections can be made in a file using the command -goto: :. Note that start and size refer to bytes and any of the standard numeric formats are accepted. For example, to select 4 bytes starting from address 16 use:
010editor -select:16:4
If start is empty, the selection is started from the current caret position which can be controlled with the -goto command. For example, to select 0x200 bytes starting from the caret position use:
010editor -select::0x200
