-Rio tips and tricks
-===================
-
-Filename completion is available with CTRL+F. To go from anywhere back to the command prompt, use CTRL+B.
-More information about shortcuts and keys in general is available in `rio(1)` and `keyboard(6)`.
-
-Command `"` prints the last used command.
-`""` _executes_ the last command.
-Both accept an optional argument to match a command string, ie:
-
- term% touch /tmp/1
- term% lc /tmp
- 1
- term% "
- term% lc /tmp
- term% ""
- term% lc /tmp
- 1
- term% "" to
- term% touch /tmp/1
- term% "" l
- term% lc /tmp
- 1
-
-Hint: `grep '^term% ' /dev/text`.
-
-If there is a command you want to run repeatedly, it's easy to define a rc function and use it instead:
-
- fn t { mk && ./6.out some arguments here >log && grep something log }- t
-
-To change the function without having to search it in the window, run `whatis t`, then redefined it.
-`ls /env/fn*` will show which functions are defined.
-
-To clear the window from any text run `echo >/dev/text`.
-
-If you need to snarf an output of some command, instead of outputting into the window and then using mouse,
-consider doing it directly instead: `command arg arg >/dev/snarf`.
-
-Want to do advanced searching on window's text? Run your favorite text editor on it: `sam /dev/text`.
-
-Want to take a screenshot of a window, but no idea which id that window has? Try seaching by its label:
-`grep sam /dev/wsys/*/label`. Replace the `label` in the path to `window` and take the screenshot:
-`topng </dev/wsys/X/window >/n/mycoolblog.com/www/files/acme.png`.
-
-When it gets difficult to work with too many windows on the screen, consider running `winwatch` and using one
-nested `rio` per virtual "workspace". If you're into keyboard-controlled window managers with virtual
-desktops, try out [riow](https://git.sr.ht/~ft/riow).

+
+## Random facts
+
+`cat input | something >output` or `something <input >output`? Prefer the latter as it requires
+less resources. It also allows the `something` program to use `input` as a normal file rather than
+a pipe, ie it is able to have random file access, while with pipes all it can do is read the file
+in sequential order.
