Command multi-select

[Crystalwarrior]

Selecting multiple commands and being able to perform right-click commands on that group, for example selecting like 5 commands and Copying would result in the Paste option pasting them in the same order they were selected.

If there are gaps in selection, it'll just put them closer together on paste.
