[Stratoscope]

The trick I use if I'm writing anything more than one paragraph is to write it first in my #mike personal channel (easy to get to with Ctrl+K or Cmd+K), and then copy and paste it to the channel it's intended for.

This way I don't have to worry about hitting Enter at the wrong time. I can also preview the message so I see exactly how it will be formatted, and no one has to see the "mike is typing" messages while I edit.

I also went to the extreme of creating a private Slack team just for myself. I was using the personal channel trick and found that if I included an image in my talking-to-myself message, and then pasted it to another channel, it didn't automatically display the image in that channel. I guess Slack figured the image had already been displayed somewhere within the team even though it wasn't in a public or private channel. I have a feeling this has been fixed by now.
