I have 2 related questions regarding Maya hotkeys.

One... it seems the default hotkey arrangement from Maya doesn't map very many menu items. For example, a list of mappings for the "edit mesh" category shows only:
Ctrl Alt ... Press PolySpinEdgeForward
Ctrl Alt ... Press PolySpinEdgeBackward
but would it not make sense for default Maya to have hotkeys for frequently used mesh editing actions like insert or move edge loop tool? Are there simply not enough key combinations (even with ALT etc...) to cover even a restricted set of widely used tools? So Maya let's the user decide based on his/her Maya useage?

Two... rather than a new user setting up his/her own hotkeys based on personal taste, are there any "standard" mappings in the Maya community that a new Maya user is encouraged to use? For example, a suggested or standard hotkey arrangement for mesh editing?

Thanks ahead of time !!!
