How to read keymap tables

Description
How to read default keymaps.

Here is a typical default keymap display for an action:

The columns represent each interactive emulator. The rows represent the two basic operational modes, 3270 and NVT.

If an entry is missing, then there is no key that maps to that action.

If a key has a modifier in front of it (Shift, Ctrl or Alt), it refers to the modifier key pressed at the same time as the base key.

In more than one key is listed, separated by a +, it refers a multi-key sequence: pressing and releasing each key (or modifer and key) in sequence.

If more than one key is listed in a vertically-stacked list, it means that there is more than one key is mapped to that action.
