Remember that vim is either in COMMAND mode or in INSERT mode. Assuming you executed ~glancast/setuplogin already, syntax highlighting should be turned on and - INSERT - will appear at the bototm of the window when you are in that mode; otherwise, in COMMAND mode, nothing appears there.
Also you should see a + in the status bar if you have made changes to the file that have not yet been saved.
These commands are all entered when in COMMAND mode by type a colon and then the name of the command:
Opens a new window with help info.
Close (quit) the file (in the current window, if more than one).
Save (write) any changes made to the file in the current window.
Close (quit) the file even if some changes have not been made. The changes will not be saved.
Split the current window and start edit file_name in the new window.
Compile by executing make utility to build the target.
List compiler errors - line numbers and message, after using the :make command.
Move the cursor to the current error.
Move the cursor to the next error.
Move the cursor to the previous error.
Show all the errors in a new window.
These commands are not preceded by a colon. The first assumes vim is in INSERT mode. The rest assume COMMAND mode:
Change to INSERT mode at the current cursor postion.
Get out of INSERT mode.
Save changes and exit vim. Like :w followed by :q
Delete the character under the cursor.
Delete the current line.
"Go" to line n
So 1G means go to the beginning of the file.
G with no line number means go to the end of the file.
Switch cursor to the next window (cycles to first window after last window is reached).
Close the current window.
Make the current window the only one; close all others.
