Hi and welcome.
There exist sticky posts which answer often issued questions like yours already and describe what you should ask where.
Please read BEFORE asking addon&library questions/post bugs/want to remove your addon
-> If you have a specific addon related question or bug report
Means:
Please ask addon related questions in the addon comments, and read the addon's description page as it should tell you how it works.
At the top right side of this website you'll find the addon search. Enter the name there and you'll get to the addon's description page:
https://www.esoui.com/downloads/info...ickMapNav.html
btw:
Most addons rely on a settings menu (called LibAddonMenu) which you are able to see if you press the ESC key ingame, and navigate to the addon settings menu at the left side.
There you'll be able to configure the addons which use this settings library LibAddonMenu.
If there are keybindings available you'll find them at ESC -> controls
For that particular addon QuickMapNav it should automatically show you the surrounding map names if you open the map.
Maybe it only works within keyboard / gamepad mode. You need to check the addon description for that as keyboard orgamepad mode often are quite different and not each addon supports both, most only support keyboard mode.
If the map names do not show it most probably is a setting you need to enable at the settings menu.
Edit:
The addon descriptions tells you some settings are off by default so you need to enable it
