//! Visual mode commands - entry, exit, selection manipulation, and operators.
//!
//! This module provides commands for visual mode operation:
//! - Mode entry: enter visual, visual-line, visual-block
//! - Mode exit: exit visual mode
//! - Selection manipulation: swap anchor/cursor, mode switching
//! - Selection operators: delete, yank, change, indent, dedent
//!
//! # Visual Mode Philosophy
//!
//! Visual mode commands follow Vim semantics:
//! - `v` enters character-wise selection from cursor position
//! - `V` enters line-wise selection
//! - `Ctrl-V` enters block (rectangular) selection
//! - `Esc` exits visual mode, clearing selection
//! - `o` swaps cursor and anchor positions
//! - `d` deletes selection
//! - `y` yanks selection
//! - `c` changes selection (delete + insert mode)
