Using CTRL/CMD+UP to reply to a message

A couple of ideas for /r would be:

• /r last reply
• /r1 second to last reply
• etc ...

Could also use /r to bring up the context (like the slash commands), and then use arrow keys or tab (and shift+tab) to toggle through the list. They could be combined as well:/r4would bring up the 4th previous message to reply to, but when you realized you wanted/r5, just hituportab... or backspace then5.

The only windows Apps that use META keys that I'm aware of are SublimeText and Atom. They both use CTRL+Pto bring up a _Go To Anything_ menu that you can type into to search actions that are available. They also both useCTRL+K to initiate and then follow with another key to execute some custom text editing commands:

• U: Uppercase the selection
• L: Lowercase the selection
• There's many more ...

Good to know about the origin of the commands that have been chosen. I've never been a big user of IRC, just used it when necessary. I did know about slack and knew you were mirroring them, but doesn't mean I agree. Too each their own though. Best to follow suit with the other major players imho.
