Overwrite Input Mode (Linear Display only)
You can select either insert or overwrite as the input mode, but only while
Linear Display is selected. In the overwrite mode, text you input replaces the
text at the current cursor location. You can toggle between the insert and
overwrite modes by performing the operations: )(INS). The cursor
appears as “
I” in the insert mode and as “ ” in the overwrite mode.
Note: Natural Display always uses the insert mode, so changing display
format from Linear Display to Natural Display will automatically switch to
the insert mode.
Correcting and Clearing an Expression
To delete a single character or function: Move the cursor so it is directly to
the right of the character or function you want to delete, and then press ).
In the overwrite mode, move the cursor so it is directly under the character
or function you want to delete, and then press ).
To insert a character or function into a calculation: Use B and C to
move the cursor to the location where you want to insert the character or
function and then input it. Be sure always to use the insert mode if Linear
Display is selected.
To clear all of the calculation you are inputting: Press .
