Radial menu

A radial menu opens around the pointer rather than beside it, and that single decision changes what choosing feels like. Every item is the same short distance away, so no option is cheaper to reach than any other and none of them needs to be read in order. The item is identified by the direction you travel, and the wedge is as large as the angle it owns, which makes it a very forgiving target compared with a row in a list. Most implementations add a dead zone at the centre: travel far enough and a direction counts, release inside the hub and nothing runs, which gives the gesture a built in cancel that costs no extra control.

The list version of the same trigger is the context menu, and the comparison is the whole argument. A list can hold twenty commands, group them with separators, nest submenus, and carry keyboard shortcuts down the right hand edge; a radial menu can hold about six before the labels start fighting for arc, and it has nowhere to put a long one. What it buys instead is speed and muscle memory: the same command always lies in the same direction, which is a thing a hand can learn and a sorted list can never offer, because a list reorders itself the moment its contents change.

That learning is what the marking menu is built on. A marking menu is this component after the reader no longer needs to see it: hold still and the ring is drawn, stroke the direction straight away and the choice is made without the menu ever appearing. The two terms are worth keeping apart, because one names the drawn thing and the other names the gesture that outgrows it. A speed dial is a third relative, a fan of actions off a single button, but it is anchored to that button rather than to wherever you pressed, and it is picked by tapping an item rather than by direction.

The pattern is common in tools where the pointer is already doing the work and rare almost everywhere else: 3D and CAD applications, Blender’s pie menus, the radial weapon and emote wheels of games, a few drawing apps on tablets. The web has almost none, for reasons worth taking seriously. There is no honest keyboard or screen reader equivalent of “north east”, so the commands have to exist somewhere linear as well, which means building both. It needs a press and hold or a right click to invoke, so it is undiscoverable to anyone who does not already know it is there. And it wants room in every direction, which the corners and edges of a document rarely have.
