The command "Ctrl + H" refers to holding down the Control key on a keyboard and pressing the "H" key simultaneously. This command commonly has two main functions:

1. Find and Replace: In many text editors or word processors, pressing "Ctrl + H" opens the Find and Replace dialog box. This feature allows the user to search for a specific word, phrase, or character in a document and replace it with another. It is particularly useful when you want to make multiple changes at once instead of manually going through the entire document.

2. Clear Formatting: In some applications or text fields, pressing "Ctrl + H" can also clear formatting. This means it removes any font styles, sizes, colors, or other formatting elements applied to the selected text and restores it to the default formatting settings. This is handy when you copy and paste text from various sources that have different formatting styles.
