1918 In other words, switch-frame events caused by events in FRAME will

1920 FOCUS-FRAME after reading an event typed at FRAME.
1922 If FOCUS-FRAME is omitted or nil, any existing redirection is
1923 canceled, and the frame again receives its own keystrokes.
1925 Focus redirection is useful for temporarily redirecting keystrokes to
1926 a surrogate minibuffer frame when a frame doesn't have its own
1927 minibuffer window.
1929 A frame's focus redirection can be changed by `select-frame'. If frame
1930 FOO is selected, and then a different frame BAR is selected, any
1931 frames redirecting their focus to FOO are shifted to redirect their
1932 focus to BAR. This allows focus redirection to work properly when the
1933 user switches from one frame to another using `select-window'.
1935 This means that a frame whose focus is redirected to itself is treated
1936 differently from a frame whose focus is redirected to nil; the former
1937 is affected by `select-frame', while the latter is not.
1939 The redirection lasts until `redirect-frame-focus' is called to change it. */)
