Mappings *gdb-mappings*
The gdb() function accepts a string as single argument which is sent to GDB as
a GDB command. This can be used to map any command to a key sequence. Examples
of such mappings are given in 'macros/gdb_mappings.vim'. To use those
mappings, source the script: >
vim normal模式下装载gdb：
:run macros/gdb_mappings.vim
F7开启键映射
The key <F7> is used to toggle between the 'gdb_mappings.vim' mappings and the
default Vim mappings.
List of key mappings in 'gdb_mappings.vim':

assembly buffers.
