Standard custom keyboards are applied to all screens displayed. If there are multiple keyboards, swipe between them or use the navigation arrows to switch between the keyboards.
Keyboards are part of the configuration that GSW ConnectBot downloads from GSW LADS. In %gsw_lads_root%\files\configs\download , there is a keyboards directory in each of the configuration folders. By default, the keyboards directory contains GSW keyboards (*.xml files) in both portrait and landscape for QWERTY, Special Keys, and Symbols. Each time GSW ConnectBot downloads a configuration from GSW LADS, keyboard xml files are transferred between GSW ConnectBot and GSW LADS.
