nvim:tldr:83165

This command is used in the context of text editing or search and replace operations in various applications or programming environments that support Vim-like command mode.

Here's a breakdown of the components of this command:

1. <Esc>: This represents the "Escape" key, which is often used to exit insert or command mode and return to normal mode in Vim-inspired editors.

2. :%s/: This tells Vim or a compatible editor to perform a search and replace operation on the entire file. The % symbol is a range specifier that specifies the entire file.

3. ${regular_expression}: This placeholder should be replaced with a regular expression pattern that represents the text you want to search for. Regular expressions are a powerful tool for pattern matching and can be used to match specific strings or patterns of strings.

4. ${replacement}: This placeholder should be replaced with the text you want to replace the matched pattern with.

5. /g: The g flag at the end of the command stands for "global" and it instructs the editor to perform the substitution for all occurrences of the regular expression within each line, not just the first occurrence.

6. <Enter>: This represents the "Enter" or "Return" key, used to execute the command.

When put together and executed, this command searches for all occurrences of the regular expression pattern within the entire file and replaces them with the specified replacement text.
