Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right.
