Many of the two-dimensional typesetting features are mapped to Ctrl key
shortcuts rather than escape-key aliases.  For example, to start a
fraction, you enter the numerator and then type Ctrl-/.  Enter your
denominator and then hit Ctrl-Space to get out of the denominator.

A walkthrough of several two-dimensional editing operations are listed in
the online help.  You can access this information by evaluating the
expression:

FrontEndExecute[
  FrontEnd`HelpBrowserLookup[
   "OtherInformation",
   "Fractions"
  ]
]

If you want to define escape-key input aliases, you will need to use the
InputAliases option, which is documented in the online help, too.

FrontEndExecute[
  FrontEnd`HelpBrowserLookup[
   "OtherInformation",
   "InputAliases"
  ]
]
