How to leave breadcrumbs for yourself when using PowerShell interactively ...
As in you typed in/pasted something long/complex, how do you find it again in your persistent PowerShell history (so survives reboots)?
If you can't remember the cmdlet, parameter text, etc, leave your own breadcrumb in a # comment on the command - to find it again, hit ctrl r then type the breadcrumb text to find that command
I use ## instead of # as part of my coding "style" - there is no difference in functionality/commentness
