On a text terminal, you can optionally access the menu-bar menus in
the echo area. To this end, customize the variable
@code{tty-menu-open-use-tmm} to a non-@code{nil} value. Then typing
-@kbd{M-`} or @key{F10} will run the command @code{tmm-menubar} instead
-of dropping down the menu. This lets you select a menu item with the
-keyboard. A provisional choice appears in the echo area. You can use
-the up and down arrow keys to move through the menu to different
-items, and then you can type @key{RET} to select the item. Each menu
-item is also designated by a letter or digit (usually the initial of
-some word in the item's name). This letter or digit is separated from
-the item name by @samp{==>}. You can type the item's letter or digit
-to select the item.
