I can't seem to copy the name of a channel in Slack!
I've tried:
Any suggestions?
This question will probably no longer be asked, because an intuitive way to copy channel name has been added by Slack since my original answer. For completeness, listing it here.
Simply right click the channel name and select Copy name. This works pretty in every place: sidebar, top bar (under search), channel reference in a message. Another option is using More -> Copy channel name in channel details panel on the right.
Open the channel whose name you want to copy and hover over the name. When the cursor changes from arrow to hand, you will be able to select the name of the channel and copy it as usual (Ctrl/Cmd+C or select Copy from context menu).
The screenshot is from the desktop app, but this works in a browser as well.
