the CLR (clear) key or a new character is inserted before
the character in the reverse video field.

Pushing the DEL key deletes the entire scratchpad entry.

The editing mode is exited when the scratchpad entry is
moved to a line by pushing a line select key.
Advisory and alerting messages are displayed in the scratchpad. A
liquid crystal display (LCD) bright/dim control bar is also displayed in the

Line Select Keys (LSK)
There are six line select keys on each side of the MCDU display. Data
is selected to a line from the scratchpad or vice--versa using the LSKs.
These keys are identified from top to bottom as 1L through 6L on the
left side and 1R through 6R on the right side. The line select keys are
the most often used keys on the MCDU.
Direct Access Prompts/Function Selects -- In the case of an
D
index display, the LSKs are used in selecting functions from the
index. In displays other than index, the bottom LSKs (6L, 6R) are
primarily used for direct access to other functions in the FMS. The
functions most likely to be accessed from the present page and
phase of flight are displayed as prompts. An example is the
ARRIVAL prompt displayed on the active flight plan pages when
within 200 nautical miles (NM) of the destination. These types of
prompts reduce the number of key strokes to minimize pilot
workload. The pilot also accesses functions through the main
navigation and performance indices.
