What
The chat prompt gained a second submit action that queues what you have typed rather than sending it right away. It ships bound by default as "ctrl+x enter": "chat:queueSubmit" and is available in the list of chat actions you can rebind. Nothing gates it, so it works for everyone on this build.
Details
chat:queueSubmitis registered in the default keymap and added to the bindable chat action list.- The ordinary
chat:submithandler was reworked to run a guard check before submitting. - Neither the action name nor the binding existed in the previous build.
Evidence
"ctrl+x enter": "chat:queueSubmit"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
