Q:

How do you make "Quick Links" web part links open in same tab/window (for lists and document libraries)?

I would like my "Quick LINKS" web part links to open in the same tab/window just as the "Quick LAUNCH" navigation bar links open in the same tab/window.
I have found that "Pages" in my site linked to quick link web part open in the same tab/window. Lists and libraries open in a new tab.
This is a team site, classic template, using modern experience.

A:

Is it this issue you are facing : https://sharepoint.uservoice.com/forums/329214-sites-and-collaboration/suggestions/17978740-stop-opening-links-in-new-tab-in-modern-pages
In that case it seems like you will have to wait for Microsoft to fix it.
On a classic page this could be fixed by injecting a js script, but that is not an option on modern pages :-(
