What key on a Mac keyboard corresponds to the ⇥ symbol?

I was looking at PyCharm documentation which says the following:

To change indentation of a text fragment, do one of the following

On the main menu, choose Edit | Indent Selection / Edit | Unindent Selection. Press ⇥ / ⇧⇥.

What is the ⇥ key on the Mac? I don't see this symbol on the keyboard.

tab        

Press ⇥ / ⇧⇥.

Firefox on Windows displays the following:

What is the ⇥ key on the mac, I can't find such a key on the keyboard?

On other Mac keyboards that key is labelled tab

I've had similar problems interpreting Mac keyboard shortcuts, and I found the following list to be useful:

Looking at the source for that page, it shows the following code (indentation mine)

<kbd 
    data-default="Tab" 
    data-default_for_gnome="Tab" 
    data-default_for_kde="Tab" 
    data-default_for_xwin="Tab" 
    data-emacs="Tab" 
    data-visual_studio="Tab" 
    data-netbeans_6.5="N/A" 
    data-eclipse="Tab" 
    data-mac_os_x_10.5_="⇥" 
    data-mac_os_x="⇥" 
    data-eclipse_mac_os_x="⇥" 
    data-intellij_idea_classic_os_x="N/A" 
    data-xcode="N/A" 
    data-resharper="N/A" 
    data-resharper_osx="N/A"
>
Tab
</kbd>

Judging by this, I'd say your browser is doing exactly what it was told, and that they definitely intended for you to use the tab key.
