-abbr -a -g gco git checkout
-\endfish
+
+
+::
+
+    abbr -a -g gco git checkout

 Add a new abbreviation where `gco` will be replaced with `git checkout` global to the current shell. This abbreviation will not be automatically visible to other shells unless the same command is run in those shells (such as when executing the commands in config.fish).
 
-\fish
-abbr -a -U l less
-\endfish
+
+
+::
+
+    abbr -a -U l less
+
 Add a new abbreviation where `l` will be replaced with `less` universal so all shells. Note that you omit the `-U` since it is the default.
 
-\fish
-abbr -r gco gch
-\endfish
+
+
+::
+
+    abbr -r gco gch
+
 Renames an existing abbreviation from `gco` to `gch`.
 
-\fish
-abbr -e gco
-\endfish
+
+
+::
+
+    abbr -e gco
+
 Erase the `gco` abbreviation.

 Defining an abbreviation with global scope is slightly faster than universal scope (which is the default). But in general you'll only want to use the global scope when defining abbreviations in a startup script like `~/.config/fish/config.fish` like this:
 
-\fish
-if status --is-interactive
-    abbr --add --global first 'echo my first abbreviation'
-    abbr --add --global second 'echo my second abbreviation'
-    abbr --add --global gco git checkout
-    # etcetera
-end
-\endfish
+
+
+::
+
+    if status --is-interactive
+        abbr --add --global first 'echo my first abbreviation'
+        abbr --add --global second 'echo my second abbreviation'
+        abbr --add --global gco git checkout
+        # etcetera
+    end
+
 
 You can create abbreviations interactively and they will be visible to other fish sessions if you use the `-U` or `--universal` flag or don't explicitly specify the scope and the abbreviation isn't already defined with global scope. If you want it to be visible only to the current shell use the `-g` or `--global` flag.
