IBM 3174 User Manual

Use the Insert key (which you are already familiar with)
to insert the word "last" into the following sample sentence.
Insert it just in front of the word "time".
After you type the word "last", press
the Backspace Delete key to undo the insertion.
Every time you press the key, you delete the previous
character and back up the cursor by one position.
The Backspace Delete key has the arrow that points left.
You can find it on the top row of the keyboard just above
the backtab key.
Remember, this function operates only while insert mode is set.
Sample Sentence: This is the time.
We also need to understand how word wrap works when insert
mode is set.
Do the following for practice:
Turn on insert mode and make sure that word wrap is on.
Insert enough words into the first sample sentence
below to force a word into the right margin and see how
word wrap works in insert mode.
The words wrap out of the first line into the second
line as long as there are sufficient spaces or
nulls on the second line to accommodate them.
When the next line cannot accommodate the word, the
keyboard locks.
Sample Sentence: This is a sentence.
This is a sample sentence.
Now let's try the cursor position indicator function.
Press the CURS PCS key.
The current position of the cursor is displayed in the
bottom row of the screen in the form rr/cc.
The letters "rr" mean the number of the row.
The letters "cc" mean the number of the column.
The rr/cc value remains displayed as long as you hold down
the ALT Shift key.
Remember that line formats
(margins, tab settings, and an "end of line" signal setting)
are remembered as long as power remains on at the control unit,
