	1 universcroll
	2 ============
	3
	4 Description
	5 -----------
	6 With scroll(1) and default binds (as of 0.8.4), how to scroll?
	7 - Inside alt screen? Mouse{4,5} to scroll {Up,Down}. :)
	8 - Outside alt screen? Shift+Mouse{4,5} to scroll {Up,Down}. :(
	9
	10 With universcroll patch, always use Mouse{4,5} to scroll {Up,Down}.
	11 Doesn't matter alt screen or not. No more `^Y^Y^Y^Y^Y^E^E^E^E^E`!
	12
	13 `universcroll-example` on top of `universcroll` makes some extra
	14 changes:
	15 - Set scroll program = "scroll"
	16 - Mouse wheel scroll enabled only with NO_MOD.
	17 - Mouse wheel zoom enabled with ShiftMask/ANY_MOD.

	24 Notes
	25 -----
	26 In the provided config, both Mouse{4,5} and Shift+{Page_Up,Page_Down}
	27 emit {`\033[5;2~`,`\033[6;2~`}. In default scroll(1) config, those
	28 sequences scroll {Up,Down} by full page each time (like TTY). This is
	29 maybe not desired behavior.
	30
	31 You can change st(1) config to use different sequences and define how
	32 scroll(1) responds to sequences in scroll(1)'s config.
	33
	34 In st(1) config, some keys are defined to send certain sequences in
	35 `key[]`. Inside `mshortcuts[]` and `shortcuts[]`, use function `ttysend`
	36 with argument `{.s = ""}` to send sequences.
	37
	38 My settings:
	39 //st
	40 { XK_NO_MOD, Button4, ttysend, {.s = "\033[1;3A"}, …
	41 { XK_NO_MOD, Button5, ttysend, {.s = "\033[1;3B"}, …
	42 //scroll
	43 {"\033[1;3A", SCROLL_UP, 3}, /* Mod1+Up */
	44 {"\033[1;3B", SCROLL_DOWN, 3}, /* Mod1+Down */

	46 Bugs
	47 ----
	48 Non-readline shell (zsh, fish) can have prompt issues with scroll(1)
	49 (Scrolling down by line after scrolling up, among other things). More
	50 problems with non-PS1 prompt.

	56 `universcroll` was made possible by
	57 [scrollback-mouse-altscreen](../scrollback). All alt screen detection
	58 code is from that patch.
