# The keyboard

Varkon will work with most types of keyboards. Keys with special meaning are described below.

## RETURN (CR or Enter)

Rejects input, exits the current situation and returns to the previous state of input.

## TAB

Similar to RETURN but returns back to the main menu. If a text input window is active the TAB key moves between text fields.

## Arrow keys

Left and right arrows are used to move the text cursor within a line. Up and down arrows are used to move the text cursor between fields in a multiple field input window.

## BS and DEL

BS (backspace) erases text from right to left. DEL (delete) erases text from right to left.

## End and Home

The End key moves the text cursor to the end of the line. The Home key moves the text cursor to the beginning of the line.

## Special keys during mouse input

During entity selections, when the mouse is used in a graphics window to select a single entity the following keys (defined by t-strings in the menu file) can be used to restrict the selection to a specific type of entity:

Key | t-string | Description
--- | --- | ---
p | t80 | Closest point
l | t81 | Closest line
a | t82 | Closest arc
c | t83 | Closest curve
s | t84 | Closest surface
b | t96 | Closest b_plane
m | t79 | Closest mesh
C | t85 | Closest coordinate system
t | t86 | Closest text
L | t87 | Closest linear dimension
D | t88 | Closest diameter dimension
R | t89 | Closest radius dimension
A | t90 | Closest angular dimension
X | t91 | Closest hatch
P | t95 | Closest part
i | t97 | Enter identity as text
SPACE | t99 | Any type of entity

During input of positions with the cursor the "g" key (t93) can be used to snap to the closest grid point even if the grid is is not active.
