+## Config File
+
+If you don't have a `~/.config/lf/lfrc` file, you can probably find an example in `/usr/share/examples/lf`.
+
+```bash
+cp -r /usr/share/examples/lf ~/.config/
+```
+
+Go straight to root with two keys.
+
+```bash
+map g/ cd /
+```
+
+Have lf open a file with the default program when you press 'o', using the program `mimeo`.
+
+```bash
+map o &mimeo $f
+```
+
+Change that default text editor to look at the extension first.
+
+```bash
+cmd open ${{
+    case $(file --mime-type $f -b) in
+        application/x-sc) sc-im $fx;;
+        text/html) w3m $fx;;
+        text/*) $EDITOR $fx;;
+        video/*) nohup mpv $fx --really-quiet >/dev/null &;;
+        *) nohup $OPENER $fx >/dev/null &;;
+    esac
+}}
+```
+
+The idea here is to use the default `$OPENER` for lf, but first check extensions.
+Note the extra `mpv` commands to leave the video to play, without blocking the terminal.
+
+### Interesting Options
+
+You can set the screen ratio with
+`set ratios 1:2:3`
+
+That leaves it as a small initial pane, a medium pane, and a large pane for file previews.
+
+### Rename
+ 
+The standard renaming is bad, because you have to re-type the file extension.
+Use this instead:
+
+```bash
+# rename current file without overwrite
+cmd rename %echo 'name: ' ; read name ; extension="${f##*.}" && newname="$name.$extension"; [ "$f" = "$extension" ] && newname="$name"; [ ! -e "$newname" ] && mv "$f" "$newname" || echo file exists
+map r push :rename<enter>
+```
+
+If you try to rename `image_1.png` with this command, you can type in `cats`, and the result will be `cats.png`.
+
+## Image Previews
+
+First, install `ueberzug` (to show images).
+Then clone the lfrun repo.
+
+```bash
+git clone https://github.com/cirala/lfimg.git
+
+cd lfimg
+
+sudo make install
+```
+

-Shut it down with the 'kill' command and the session's number:

-This will forward over port 5900+x where x is the session number.  For the first server, that's port 5901.
