Hi Georg, I'm not terribly familiar with ui.gadgets, but I can at least help you figure out what's going on here.
The word `handle-gesture` is generic (http://docs.factorcode.org/content/word-handle-gesture,ui.gestures.html), so it does different things depending on its argument classes. You can tell whether an `editor` object will handle a given gesture with `handles-gesture?` (http://docs.factorcode.org/content/word-handles-gesture__que__,ui.gestures.html) `T{ key-down { sym "HOME" } } <editor> handles-gesture?` is `t` because `editor` handles `HOME`, but the same code with `T{ key-down { sym "a" } }` is `f`. `editor` is a subclass of `line-gadget`, but `handle-gesture` defines a method on neither of these classes (see the above linked documentation). This can be proven by writing `M\ line-gadget handle-gesture` and `M\ editor handle-gesture` both of which throw a `method-lookup-failed` error. `handle-gesture` defines `M\ object handle-gesture` though, and that method definition is `[ nip ] [ get-gesture-handler ] 2bi dup [ ( gadget -- ) call-effect f ] [ 2drop t ] if`. The important part of that is `get-gesture-handler`, the same word used by `handles-gesture?`. `get-gesture-handler` looks at the `gestures` word property (http://docs.factorcode.org/content/word-word-prop,words.html) of the superclasses of the input `gadget` object. In the same way you can see what keys have gestures defined with `editor "gestures" word-prop .`, which is a long table like `H{ { cut-action [ \ com-cut invoke-command ] } { redo-action [ \ com-redo invoke-command ] } { T{ key-down f f "BACKSPACE" } [ \ delete-previous-character invoke-command ] } ...` It contains exclusively line-editing commands like`C+l` for select line but no input keys like `1`. Some keys are defined by default, others are not -- I don't know why, but another person will probably reply to tell you why. Hopefully it is somewhat enlightening! ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On July 2, 2018 8:00 AM, Georg Simon georg.si...@auge.de wrote: > T{ key-down { sym "HOME" } } <editor> handle-gesture . > > prints f as the gesture was handled.
