Sedt is a UNIX editor that functions (nearly) identically to the edt editor found on many VAX systems. It is supported in order to provide a simpler transition for users of VMS to the UNIX systems. Sedt works best if it thinks it's running on a vt100 terminal. Thus, before running sedt, you should execute the following command in your terminal window (see the C shell document for details):
setenv TERM vt100
Depending on what programs you typically use and which terminals you typically log into, you might want to include the above command in your .cshrc file (this file sets a number of defaults for your account when you log in). Please consult the UNIX help file for more information.
To start the sedt editor, simply type
sedt filename
where filename is the name of the file you wish to edit. The screen will be filled with the first lines of the file. If you leave off the filename, then sedt will create a new unnamed file. If the file you specify does not exist, then sedt will create a new file, and assign it the given name.
In describing key sequences for commands, the PF1 key (upper left key on the numeric keypad) will be referred to as GOLD and functions similarly to the control and alt keys; i.e. the description
GOLD PF3
means press the GOLD (PF1) key and then press PF3. Unlike the control and alt keys, you do not have to hold the GOLD key down while pressing the key it modifies. The number keys on the keypad are referred to by KP0, KP1, ..., KP9, KP+, KP-, KP, , KP., and ENTER. The most important key to remember is PF2 which invokes the help displays.
To exit from sedt, press the F8 key found at the top of your keyboard. If there are unsaved changes, you will be asked whether or not you really want to quit. Answer yes or no as appropriate. To save your work, press the F6 key. Sedt indicates whether or not there are unsaved changes in the bottom right of your screen. If you see Mod=<num>, then there are unsaved changes. If there is no number following the text Mod=, then your editing has been saved.
Almost all cursor movement commands make use of the default direction which is indicated in the bottom left of your screen. The default direction is either forward (indicated by Fwd or reverse (Rev). The default direction is set by KP4 (forward) and KP5 (reverse).
Assuming the default direction is set as you want, movement consists of pressing the appropriate key for the amount of distance you wish to move the cursor. For example, KP0 moves by a line, KP1 moves by word, and KP7 moves a page at a time.
Key Action GOLD M Set mark GOLD m GOLD . Goto mark KP0 Goto beginning of next line KP1 Goto next word KP2 Goto next end of line KP3 Goto next character KP4 Set default direction forward GOLD KP4 Goto the end of the buffer KP5 Set default direction reverse GOLD KP5 Goto the beginning of the buffer KP7 Goto next page KP8 Goto next paragraph GOLD F19 Goto matching bracketing character
To include more typing in a document, simply move the cursor to where you wish to add text and begin typing. You can cut and paste sections of text as follows:
Other text insertion commands are summarized below.
Key Action ^I Insert a tab character ^M Insert a carriage return GOLD G Include file at current position GOLD g (sedt prompts for file name) GOLD P Insert a form feed character GOLD p F11 Insert an escape character GOLD KP6 Paste GOLD KP0 Open line GOLD KP3 Insert ASCII character GOLD KP, Undelete character GOLD KP- Undelete word GOLD PF4 Undelete line
There are several ways to leave sedt. These are summarized below.
Command Action F10 Save buffer and exit GOLD F GOLD f F8 Quit without saving buffer GOLD Q GOLD q F6 Save contents of buffer F7 Save context and contents of buffer
The delete commands allow for deletion by word, character, line, etc. as well as cutting arbitrary stretches of text. See the section on inserting text for instructions on cut-and-paste. The commands are summarized below.
Command Action F13 Delete to beginning of wordU Delete to beginning of line GOLD Z Clear buffer GOLD z KP6 Cut selection KP, Delete character forward KP- Delete word forward PF4 Delete line forward GOLD KP2 Delete to end of line
To find a text string press GOLD PF3. Sedt then prompts you for a string to look for. The find command then searches for that text using the default direction. To find the next occurence(s) keep pressing PF3. At any time you may change the default direction using KP4 or KP5.
To search for a new string, you must again enter GOLD PF3.
To replace a string press GOLD KP9. Sedt prompts you first for the string to replace and then for the replacement text. As in the find command, replace respects the default direction. To execute the same replacement command again, just press KP9. To define a new replacement, press GOLD KP9.
There are many other features that sedt supports including multiple buffers, rulers, defining commands, etc. For more information, consult sedt's internal help system which is accessed by pressing PF2.
