The details might get you. Honestly, you’re a competitive candidate but getting into W&M is no easy thing. Keep working hard and apply and pay attention to those details.

DEL is the DELETE key and ESC is the escape key (key F11 in G17)

C – <chr> means hold the CONTROL key while typing the character <chr>

M – <chr> means hold the ESC key down and type <chr>

Manipulating Files

Exit an emacs window permanently	C – x C – c
Read (an existing) file into emacs	C – x C – f
Save a file back to disc	C – x C – s
Insert contents of another file into this buffer	C – x i
write a buffer to a specified file	C – x C – w

Note that for the write command, the file is inserted at the cursor position.

Working within a File

Moving around: one character at a time, use arrow keys.

 

Scrolling to next screen	C – v
Scrolling to previous screen	M – v
Go to buffer beginning or end	M – < M – >

Killing and deleting

Entity to kill	backward	forward
Character	DEL	C – d
word	M – DEL	M – d
to end of line	M – 0 C – k	C – k
sentence	C – x DEL	M – k
Kill to next occurence of char	M – z	char

Error recovery

Abort partially typed or executing command	C – g
Undo an unwanted change	C – x u or C – _
Restore a buffer to its original contents	M – x revert – buffer
Redraw garbaged screen	C – l

The latter command is not only useful to redraw the screen, it also centers the screen so that the cursor is placed in the midddle of the window.

Searching:

search forward	C – s
search backward	C – r
regular expression search	C – M – s
exit incremental search	ESC
undo effect of last character	DEL
abort current search	C – g

Starting EMACS

First, make sure you are in the right sub-directory by issuing the command

> cd directory

where directory is the sub-directory you will be working on (e.g. project 1 or project 2). Once in the appropriate directory, it is a matter of creating or updating a file by the command:

> emacs answer &

This creates a window and reads the file answer if it exists; otherwise it will create the file when you save the contents of the emacs window. The & tells the system to run emacs in the background so it doesn’t lock up the xterm window.

Question: Does anyone know where I can find some good math sites that can help me find things about the history of math?

I would like answers that are not search engines just specific sites.
