            Bug ID: 85536
           Summary: Accessibility: dwell click implementation
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org

From
https://help.gnome.org/users/mousetweaks/stable/mouse-a11y-functions-description.html.en#mouse-a11y-dwell-description

"There are users that cannot use any hardware button. By activating the Dwell
Click, they can have the mouse perform the various clicks without pressing any
mouse button. The click types that can be performed are: single primary click,
double click, drag click and secondary click.
...

Each time the pointer stops moving, a dwell click is initiated."

The core is simple to implement, the tricky bit is the complex configuration
options and the feedback. From the above link "To give feedback to the user,
mousetweaks will fill the arrow of the pointer with another color while it is
counting down the time before the click completion kicks in.". This is
essentially impossible in libinput without flagging the event.

Maybe dwell click is better off as compositor option then?
