Legacy Edge offers Duplicate option in Tab context menu to open the same tab, but it doesn’t provide a keyboard shortcut for the same, whereas new Edge based on Chromium offers Ctrl+Shift+K shortcut to duplicate a tab. Microsoft allows to reopen the same tab with another shortcut Ctrl+K in new Edge in Canary and dev builds if you enable a flag.
As of now, in new Edge, Ctrl+K and Ctrl+E shortcuts are used to focus search filed in the address bar, if you enable an experimental feature that is available in Edge Canary and Dev builds, you can use Ctrl+K to duplicate a tab, here is how you can achieve that.
Assign alternate tab shortcut Ctrl+K to duplicate tabs in new Microsoft Edge browser
1. Launch Microsoft Edge Canary/Dev
2. Visit edge://flags/#edge-use-alternate-duplicate-tab-shortcut
3. Select Enabled and restart the browser.
Do note the flag has been around for a while and is not new, but as Edge Developer Ericlaw said this saves muscle memory of users coming from old Edge and new Edge users have one less keystroke to press. If you duplicate tabs most often in the new Edge, then you might find the shortcut useful.
