### TUI specific commands

The TUI has specific commands to control the text windows. These commands are always available, that is they do not depend on the current terminal mode in which GDB runs. When GDB is in the standard mode, using these commands will automatically switch in the TUI mode.

`layout next`
  Display the next layout.
`layout prev`
  Display the previous layout.
`layout src`
  Display the source window only.
`layout asm`
  Display the assembly window only.
`layout split`
  Display the source and assembly window.
`layout regs`
  Display the register window together with the source or assembly window.
`focus next | prev | src | asm | regs | split`
  Set the focus to the named window. This command allows to change the active window so that scrolling keys can be affected to another window.
`refresh`
  Refresh the screen. This is similar to using <C-L> key.
`update`
  Update the source window and the current execution point.
`winheight` name`+`count``
`winheight` name`-`count``
  Change the height of the window name by count lines. Positive counts increase the height, while negative counts decrease it.
