Hi @kaztateishi,
I’m afraid the option to navigate frames in Presentation mode with keyboard inputs/shortcuts is currently not possible. In the mean time, you can navigate between the slides by using the arrow icons or keys.
By the way, it's a popular feature request on our Community: https://community.miro.com/wish-list-32/shortcuts-and-hotkeys-for-workshop-facilitators-1903. Feel free to upvote for it to raise the awareness of our Product team. If you haven’t already, I would suggest voting for this Wish List item, which includes mention of Presentation Mode.
