From the quibbles department:

According to Approved Verbs for PowerShell Commands, the official alias prefix for Select-* cmdlets is sc, not sl (the latter is for Split-* cmdlets).

Therefore, the naming-convention-compliant alias for Select-String should be scs, not sls.

It's probably too late to remove sls, but we could add scs.

Either way, a note in the documentation would be helpful.
