Assigning frequently used functions to buttons and dials (Custom Key/Dial Set.)
You can use the custom key function to assign the functions you use most frequently to easily operable buttons and dials.
This lets you skip the process of selecting items from MENU, so you can recall the functions more quickly.
You can separately assign functions to custom keys for the still image shooting mode, movie shooting mode, and
playback mode.
Assignable functions vary depending on the buttons or dials.
You can assign functions to the following buttons and dials.
