 # Luke's build of st - the simple (suckless) terminal

+The [suckless terminal (st)](https://st.suckless.org/) with some additional features that make it literally the best terminal emulator ever:
+
+## Unique features (using dmenu)
+
++ *follow urls* by pressing `alt-l`
++ *copy urls* in the same way with `alt-y`
++ *copy the output of commands* with `alt-o`
+
+## Bindings for
+
++ *scrollback* with `alt-↑/↓` or `alt-pageup/down` or `shift` while scrolling the mouse
++ OR *vim-bindings*: scroll up/down in history with `alt-k` and `alt-j`. Faster with `alt-u`/`alt-d`.
++ *zoom/change font size*: same bindings as above, but holding down shift as well. `alt-home` returns to default
++ *copy text* with `alt-c`, *paste* is `alt-v` or `shift-insert`
+
+## Pretty stuff
 
 + Compatibility with `Xresources` and `pywal` for dynamic colors. The `Xdefaults` file shows a usage example.
 + Default [gruvbox](https://github.com/morhetz/gruvbox) colors otherwise.
-+ Transparency/alpha, which is also adjustable from `~/.Xresources`.
++ Transparency/alpha, which is also adjustable from your `Xresources`.
 + Default font is system "mono" at 16pt, meaning the font will match your system font.
-+ Very useful keybinds including:
-	+ Copy is alt-c, paste is alt-v or alt-p pastes from primary selection
-	+ Alt-l feeds all urls on screen to dmenu, so they user can choose and
-	  follow one (requires dmenu installed).
-	+ Alt-y does the same as above, but copies the url with xclip.
-	+ Zoom in/out or increase font size with Alt+Shift+k/j or u/d for larger intervals.
-	+ Hold alt and press either ↑/↓ or the vim keys k/j to move up/down in the terminal.
-	+ Shift+Mouse wheel do the same.
-	+ Alt-u and Alt-d scroll back/forward in history a page at a time.
-	+ Alt-PageUp and Alt-PageDown will do the same.
+
+## Other st patches
+
 + Vertcenter
 + Scrollback
 + updated to latest version 0.8.2
 
-The following additional bindings were added before I forked this:
-
-+ Scroll through history -- Shift+PageUp/PageDown or Shift+Mouse wheel
-+ Increase/decrease font size -- Shift+Alt+PageUp/PageDown
-+ Return to default font size -- Alt+Home
-+ Paste -- Shift+Insert
