Help me please. I don't understand how to use it.

I installed the plugin, but the menu in obsidian did not appear, I also did not find the settings in the hotkey menu. Keywords like attached GIF on my Windows PC are not working

You have to enable the plugin.

• In Obsidian, open settings.
• Go to "Community plugins"
• Scroll down until you see "Footnote Shortcut"
• Click the toggle next to it to enable the plugin

You should now see the command in the command palette, and you should be able to set a hotkey in the "Hotkeys" section of Obsidian's settings.
