 # Luke's build of st - the simple (suckless) terminal
 Forked from [https://github.com/shiva/st](https://github.com/shiva/st) for simplicity's sake, which is the [suckless terminal (st)](https://st.suckless.org/) with some patches added:
 + transparency
-+ copy to clipboard
+ copy to clipboard (alt-shift-c)
-+ ~~Solarized colors (light and dark toggleable)~~ (Change to your own colors, see no value of toggle)
+ Solarized colors (light and dark toggleable)
 + vertcenter
 + scrollback with keyboard
 + scrollback with mouse

 ## My own additions
-+ Default font is system "mono" at 14pt
+ Default font is system "mono" at 14pt, meaning the font will match your system font.
-+ Alt-k and Alt-j scroll back/foward in history one line at a time
+ Hold alt and press either ↑/↓ or the vim keys k/j to move up/down in the terminal.
-+ Alt-u and Alt-d scroll back/foward in history a page at a time

 ## Installation for newbs
 ### Requirements for build
 Install `base-devel` - compiler and stuff (most distros have).
 Install code depndencies (voidlinux - most distro should have something similar) 
 + `fontconfig-devel` 
 + `libX11-devel` 
 + `libXft-devel`
 ### Make & install
 ```
 make
 sudo make install
 ```
 Obviously, `make` is required to build. `fontconfig` is required for the default build, since it asks `fontconfig` for your system monospace font.  It might be obvious, but `libX11` and `libXft` are required as well. Chances are, you have all of this installed already.
 ## Custom changes (`config.def.h` or `config.h`)
-### Alpha
+By default, the terminal is transparent with a blackish background. There's a patch file `solarized-alpha-toggle.patch` which you can use to remove the transparency and give it a typical deep, dark blue solarized background. Just run:
-+ Change `alpha` value (86 LOC), be default set `0xcd`.
+```
-+ Less transparent set to `0xdd` or `0xee`.
+patch < solarized-alpha-toggle.patch
-+ For non transparent terminal set to `0xff`.
+```
-### Colorname
+Then, run `make` & `sudo make install` again to install the new build. You make reverse the solarized background by running the same command as above, but giving `patch` the `-R` option as well.
-+ Change `colorname[]` array values (88 LOC), default colours inspired by colors used in Pop! OS.
+## Explore `config.h`
-+ Numbers of 0 - 15 are usual terminal colors. Changed them to your liking.
+
 + Change `colorname[]` array values (88 LOC), default colours are solarized.
 + Numbers of 0 - 15 are usual terminal colors. Change them to your liking.
 + Change `bg` to your desired terminal background color.
 + Change `fg` to your desired terminal foreground color.
 + Change `cursor` to your desired terminal cursor color.
