+## Transfer file to/from MVS
+
+Let's say I have written some wise words in a file on mvs, and I want a copy on my linux machine. The MVS file name is `PETER.TEST.TEXT(WISDOM)`, and the linux file is `/tmp/wisdom.txt`. In the file transfer gui, the MVS file name must be enclosed in single quotes.
+
+* On MVS: hit F3 until you get to the READY prompt.
+* Now click `File > File transfer...` in x3270, and type in the local (linux) and host (mvs) file names. The options selected should be `Receive from host`, `Host is TSO`, `Transfer ASCII file`. I leave the rest as it is.
+* Click `Transfer File`
+* Check that it transferred the file.
+
+Example file contents:
+
+ peter@fedora:~$ cat /tmp/wisdom.txt
+ Så blev de sgu sure.
+ Det er linie.
+
+
+To transfer a file from linux to mvs, follow the same steps, but click the `Send to host` option instead.
+
+## Get back to "the main menu" (ISPF) after hitting F3 too many times
+
+Type `ispf` at the `READY` prompt.
+
+## Exit the editor when it says "SAVE not valid in VIEW mode"
+
+You have opened the editor in view mode (v), but made changes. You should probably have opened it in edit mode (e). For now, type `cancel` to discard your changes, and try again in edit mode this time.
+
+## Help, I can't type anything, and there is a big red X at the bottom of my x3270 window
+
+Hit RESET (Alt-r), and place the curser somewhere where you are allowed to type.There is also HOME (Alt-h) which is nice.
+
+## Scroll
+
+* Up: `F7`
+* Down: `F8`
+* Left: `F10`
+* Right: `F11`
