You can easily find and replace text with the FIND command
To search for and replace text, use FIND. Replacement is based on text content only; character formatting and text properties are not changed.
When searching for text in a 3D environment, the viewport will temporarily change to a 2D viewport so that text isn’t blocked by 3D objects in your drawing.
With FIND, you can use wild-card characters in your search.
| Character | Definition | 
|---|---|
| # (Pound) | Matches any numeric digit | 
| @ (At) | Matches any alphabetic character | 
| . (Period) | Matches any nonalphanumeric character | 
| * (Asterisk) | Matches any string and can be used anywhere in the search string | 
| ? (Question mark) | Matches any single character; for example, ?BC matches ABC, 3BC, and so on | 
| ~ (Tilde) | Matches anything but the pattern; for example; ~*AB*matches all strings that don't contain AB | 
| [ ] | Matches any one of the characters enclosed; for example, [AB]C matches AC and BC | 
| [~] | Matches any character not enclosed; for example, [~AB]C matches XC but not AC | 
| [-] | Specifies a range for a single character; for example, [A-G]C matches AC, BC, and so on to GC, but not HC | 
| ` (Reverse quote) | Reads the next character literally; for example, `~AB matches ~AB |
