1Q: I can't type \ or : in DOSBox.
2A: This is a known problem. It only occurs if your keyboard layout isn't US.
3   Some possible fixes:
4     1. Switch the keyboard layout of your operating system.
5     2. Use / instead.
6     3. Open dosbox.conf and change usescancodes=false to usescancodes=true.
7     4. Add the commands you want to execute to the "configfile".
8     5. Change the DOS keyboard layout (see Section 7 Keyboard Layout).
9     6. Use ALT-58 for : and ALT-92 for \.
10     7. for \ try the keys around "enter". For ":" try shift and the keys 
11        between "enter" and "l" (US keyboard layout).
12     8. Try keyb.com from FreeDOS (http://projects.freedos.net/keyb/).
13        Look for keyb2.0 pre4 as older and newer versions are known to
14        have a bug in the loader routines.
