Second click on Tab brings "Set Alias" along with "Close tab", but what is THAT alias? (I know others)

[nugged]

When I right-click on the tab, I have:

what is that for? I can’t find any docs on it or hints. What is that for?

[deathaxe]

An alias is an alternative name.

This way a repository can be represented with any name without touching the original’s repository (folder) name.

It can help distinguish repositories which use the same name on different locations.

Aha! So, the use case is to name them differently if the folder name matches.
Let me seek where that is stored, then… Aha! I see, in the Preferences.sublime-settings config file! Great.

    "repository_aliases":
    {
        "/Users/...../git_work/utilities/.git": "Team tools",
        "/Users/...../git_local/utilities/.git": "My local MacOS tools",
    },

(@deathaxe, btw any knowledge on another tab-related question (How to open duplicate tab (and why :-) ), i.e. double open the same repo)?)
