Which Terminal do you use.
I use Terminal Emulator but one issue I have is that terminal empulator doesn't recongnize the pipe key "|", when I enter this key using the softkeyboard it just gets ignored. I have emailed the developer but no reply.
The second issue I have is that there isn't a back quote key on the keyboard "`" so you can't use this to do something like this on the command line.
for FILE in `ls *.txt`
do
...something
done
and I use this trick often on command lines to manipulate several files at once. This isn't terminal emulator's fault but I thought some terminal's will provide a means for extending the keyboard. I guess I could also use a plug in keyboard which has this key if there are any.
