I also suffer from the curse of jira, and need to enter ticket numbers in my notes - especially my daily notes, where I track what I need to work on each day.
I wrote a macro where, in the work vault, when I type [ABC-123], it will immediately type (https://xxx.atlassian.net/browse/ABC-123) afterward, turning it into a link. I require typing the brackets because there are times I don’t want it converting ticket numbers to links, and because the brackets will need to end up there anyway, to make it a Markdown link.
Here’s a copy (with identifying information about $DAYJOB removed). You can’t really see it in the picture, but the “title contains” value is “SPACE DASH SPACE vaultname SPACE DASH SPACE”.
Maybe you’ll find this useful, and/or use it as an example of how to build your own macro.
