Is impossible to access "Edit -> Indent line" since it is binding to Cmd-Opt-]
On the other hand in Sp keyb. you must press Opt fot access ] or [ keys....
] = Opt-]
actually the ]-key contains the *+] chars, * is with Shift, + is the default and, I've said ] is with option.
then if you press Cmd-Opt-] you always get "Edit -> Shift right" as if you've pressed Cmd-]
