2078 FOCUS-FRAME after reading an event typed at FRAME.
2080 If FOCUS-FRAME is omitted or nil, any existing redirection is
2081 cancelled, and the frame again receives its own keystrokes.
2083 Focus redirection is useful for temporarily redirecting keystrokes to
2084 a surrogate minibuffer frame when a frame doesn't have its own
2087 A frame's focus redirection can be changed by `select-frame'. If frame
2088 FOO is selected, and then a different frame BAR is selected, any
2089 frames redirecting their focus to FOO are shifted to redirect their
2090 focus to BAR. This allows focus redirection to work properly when the
2091 user switches from one frame to another using `select-window'.
2093 This means that a frame whose focus is redirected to itself is treated
2094 differently from a frame whose focus is redirected to nil; the former
2095 is affected by `select-frame', while the latter is not.
