How to assign key W in Less to toggle -S option

Toggling word-wrap in Less requires 4 key-presses: - Shift S Enter. In other editors it requires 2 presses: Alt Z or similar.

And toggling the option repeatedly requires one key-press in these other editors.

Can I configure recent Less versions to toggle word-wrap using either one of W, Ctrl+W, Alt+W or any similar one or two-key shortcut ? Without having to also type Enter to dismiss the "Chop long lines (press ENTER)" prompt ?

Adding w toggle-option -Sn in ~/.lesskey does not get rid of the press RETURN prompt.
