Step 1. Install Tabs plugin. You might want to search for it inside the Plugins marketplace in Logseq app.
Step 2. Get rid of annoying Cmd+W shortcut that is useless in Logseq in MacOS settings:
Settings: Keyboard > App Shortcuts > Keyboard Shortcuts… > App Shortcuts. Bind “Close Window” to cmd-shift-w or anything else.
Step 3. In Logseq go to Settings > General > Keyboard Shortcuts > Plugins and set shortcuts like this:
Now you can move between open tabs with cmd+option+➡️ and cmd+option+⬅️ and close current tab with habitual cmd+w.
