+title: Read and scroll
+tags: [ "shell", "pager" ]
+---
+
+The output from `tree` is too long.
+Turn on colours and read with less:
+
+```sh
+tree -C | less -R
+```
+
+- `j`: scroll down
+- `k`: scroll up
+- `g`: go-to top
+- `G`: go-to bottom
+- `q`: quit
+
+# Search with less
+
+- `/<word>` to search
+- `<Escape>u` to undo search highlights
+
+Make search case insensitive with `less -i`.
+
+```sh
+less -i README.md
+```
+
+The `man` pages often use `less`.
+Make the `man` pages use `less` with case insensitive searching by using the `$MANPAGER` variable.
+
+```sh
+MANPAGER='less -i'
+man column
+/exampl
+```
+
+# Quick Commands
+
+Execute a shell command inside `less` so you don't have to lose your place while reading `column`.
+Just press `!`, e.g. `!ls`.
+
+
+# Edit a File
+
+While reading a file, press `v` to edit it ('v' stands of `vi`).
