Linux Command Manual

The Linux dumpkeys command is used to display the keyboard mapping table. The output can be recognized by the loadkeys command to change the mapping relationships.

Syntax

dumpkeys 

Parameter Description:

• -i Driver information (key code range, count, state keys)
• -l Detailed driver information
• -n Display in hexadecimal
• -f Display all information
• -1 Display key combinations line by line
• -S Set output format (0: default 1: complete 2: line by line 3: simple)
• --funcs-only Function key information
• --keys-only Key combination information
• --compose-only Regular key information

Examples

Display function key information:

# dumpkeys --funcs-only
string F1 = "33[[A"
string F2 = "33[[B"
string F3 = "33[[C"
string F4 = "33[[D"
