This is something perf-html has and that allow to expand a node and all its children with Alt+Click. It would be nice to have the same thing for groups in the console. This would need a couple things : - Pass a flag to the action if alt was pressed (See ) - In the action (See ), return the value of the flag - In the reducer, if flag is true, push all subgroups to `messagesUiById` (See ). Subgroups can be retrieved by looking at `groupsById`. This should be enough since visible messages are then computed based on opened groups.  http://searchfox.org/mozilla-central/rev/d441cb24482c2e5448accaf07379445059937080/devtools/client/webconsole/new-console-output/components/message.js#166  http://searchfox.org/mozilla-central/rev/d441cb24482c2e5448accaf07379445059937080/devtools/client/webconsole/new-console-output/actions/messages.js#51-56  http://searchfox.org/mozilla-central/rev/4a9f505eb849f0a646ad6c13eb669e579839b3a8/devtools/client/webconsole/new-console-output/reducers/messages.js#131
