回答1:

Create a snippet:

<snippet>
    <content><![CDATA[
${SELECTION/\s{2,}/ /g}
]]></content>
</snippet>

Then create a keybinding to call that snippet in your Preferences -> KeyBindings - User file:

{ "keys": ["ctrl+shift+z"], "command": "insert_snippet", "args": { "name": "Packages/User/Snippets/test_snippets/regex_whitespace.sublime-snippet" } },

Then, select text on a line, or multiple lines, and use the keymap.

This can also be done with a regex search and replace. First, select the text you want to alter. Next, click on Find -> Replace.... Make sure the Regex and In selection buttons are selected. To visualize what you're going to replace, you can also select the Highlight matches button as well. In the Find What field, enter (\s){2,}, and in the Replace With field, just enter a space. Click Replace All, and all instances of two or more whitespace characters will be replaced with a single space.
