# Duplicate Current Browser Tab

Let's say I'm on a specific page within a web app. Maybe I'm typing out a
comment on that page. Before I can hit submit, I need to reference something
elsewhere in the app, perhaps on the previous page.

I can `cmd+t` to open a new tab, type out the URL, hit enter, and then navigate
around until I find the page I'm looking for. I do this exact thing sometimes,
but it feels slow and clunky.

The other way I accomplish this which feels way smoother is to _duplicate the
current tab_. I can do that by `cmd`-clicking the reload button next to the URL
bar.

This opens another tab at the same URL with the same navigation history. I can
switch to that tab and hit the back button to go to the previous page, find the
thing I wanted to reference, and then return to the previous tab to finish what
I was doing.

To give a more concrete example: this happens all the time with GitHub PR
comments where I want to copy the URL or number of a specific PR to reference in
a comment I'm leaving on the current PR. Duplicating the tab, going _back_ to
the PR index view, finding the other PR, and copying its URL -- to me that is a
quicker flow popping open a fresh browser tab.
