[ST4] more convenient shortcuts

[eugenesvk]

Given that ST4 now supports chords, maybe it'd be much better to use more mnemonic and thus easier-to-remember keybinds around
^J+^key¹?
Or at least suggest these (to avoid any conflicts) in the readme/install message so that a user could easily copy&paste and customize.

For example:
^J, ^W → ace_jump_ W ord
^J, ^C → ace_jump_ C har
^J, ^L → ace_jump_ L ine
^J, ^I → ace_jump_w I thin_line
^J, ^S or S → ace_jump_ S elect
^J, ^A or C → ace_jump_ A dd_ C ursor
^J, ^E or A → ace_jump_ A ft E r

// AceJump settings for the above examples on a macOS
  {"keys":["super+j","super+w"],	"command":"ace_jump_word"},
  {"keys":["super+j","super+c"],	"command":"ace_jump_char"},
  {"keys":["super+j","super+l"],	"command":"ace_jump_line"},
  {"keys":["super+j","super+i"],	"command":"ace_jump_within_line"},
  // AceJump Modes              	//
  {"keys":["super+j","s"],      	"command":"ace_jump_select"},
  {"keys":["super+j","c"],      	"command":"ace_jump_add_cursor"},
  {"keys":["super+j","a"],      	"command":"ace_jump_after"},
