## LSP Features
### Goto Declaration (`gD`)
The LSP supports goto declaration functionality for:
- **Functions** - Jump to function definition in `.scl` files
- **Function Blocks (FB)** - Jump to FB definition in `.scl` files
- **Data Blocks (DB)** - Jump to DB definition in `.scl` and `.db` files
- **User-Defined Types (UDT)** - Jump to type definition in `.scl` and `.udt` files
Usage: Place cursor on a variable or type name and press `gD` (or use LSP client command).
