Adding the Showcmd Setting

To enable the showcmd feature in Vim, you’ll need to add a specific line to your Vim configuration file. Open your .vimrc file and insert the following setting: set showcmd. This command activates the showcmd functionality, which displays the commands you type in the status bar, providing real-time feedback on your actions.

The showcmd setting can be toggled on or off with a simple Boolean value. Here’s a quick reference for the setting:

Option          Description                     Value
-----------------------------------------------------
showcmd         [Show (partial) command](https://marketplace.visualstudio.com/items?itemName=vscodevim.vim) in status bar  true
showmodename    Show name of current mode in status bar true

Remember, after adding the showcmd setting, you must save the .vimrc file and reload your Vim configuration for the changes to take effect.
