- We Salesforce nerds have been hacking our URLs since the days of Classic (especially for handing parameters to Reports).
- I navigate Setup using bit.ly shortcuts (like bit.ly/sfsetup) that I recommend for the keyboard-obsessed.
So I see that there’s some promise in messing with Canva URLs–the typical URL when editing a Canva preso appears to look like this:
https://www.canva.com/design/[11CharDesignID]/[22CharSessionID]/edit
which, if you want to send to someone, can be simplified to
https://www.canva.com/design/[11CharDesignID]
If you want to send a link to a particular page, right-click (or Control-click on a Mac) a page in the “Pages” tray at the bottom of the screen and choose “Copy link to this page”:

. . . that gives you a URL that looks like
https://www.canva.com/design/[11CharPresoID]/[22CharSessionID]/edit?ui=[18CharSlideID]
which can be simplified and sent to someone else as
https://www.canva.com/design/[11CharPresoID]?ui=[18CharSlideID]
[edit: this trick appears to work for Canva presentations, but not Canva docs.]
