+// Select word/line button.
+//
+// Implements a button that selects the current word, assuming conventional text
+// editor hotkeys. Pressing it again extends the selection to the following
+// word. The effect is similar to word selection (W) in the Kakoune editor.
+//
+// Pressing the button with shift selects the current line, and pressing the
+// button again extends the selection to the following line.
+//
+// Note for Mac users: Windows/Linux editing hotkeys are assumed by default.
+// Uncomment the `#define MAC_HOTKEYS` line in select_word.c for Mac hotkeys.
+// The Mac implementation is untested, let me know if it has problems.
+//
+// For full documentation, see
