Why can't the exclamation mark be tabbed in sublime?

Why can’t the exclamation point in Sublime Text be automatically completed using the Tab key?

In Sublime Text, the exclamation point (!) cannot be automatically completed through the Tab key. There are two main reasons:

1. Brackets automatic completion mechanism

Sublime Text has a function to automatically complete brackets. When the user enters a bracket (, [, {, it automatically inserts the matching bracket ), ], } on the other side. The exclamation mark (!) is not a bracket character and therefore does not trigger this autocompletion mechanism.

2. Custom syntax highlighting rules

Sublime Text uses custom syntax highlighting rules to identify different language elements. These rules determine which characters in the text should be highlighted in a specific way. By default, the exclamation mark is not assigned any special syntax element and is therefore not recognized by tab completion.

Although exclamation points cannot be automatically completed using the Tab key, Sublime Text still has some ways to quickly and easily enter exclamation points:

• Enter manually: You can Type the exclamation point directly without using the Tab key.
• Snippets: You can create custom snippets that contain exclamation points. This snippet can then be inserted by entering a short trigger, eliminating the need to manually enter an exclamation point.
• Plugins: There are plugins that extend Sublime Text’s autocompletion functionality, including adding support for exclamation marks. You can install these plugins to enhance your autocomplete experience.
