Cycling tabs is not effective. PSreadline supports CTRL+SPACE completition - just type - and then CTRL+SPACE and it will show menu with ALL arguments. The same works if you start argument (i.e. -P<CTRL+SPACE> shows all params starting with P)

Ctrl-Space on PowerShell is outstanding, as long as your devs are actually properly commenting their scripts (I assume your in-house PowerShell is put into modules that get installed on user machines).

It has no relation to comments.
