* lisp/org-macs.el (org-display-buffer-split): New function to display just the new buffer and current buffer visible in the frame. To be used as `display-buffer' ACTION parameter. * lisp/org-agenda.el (org-agenda-get-restriction-and-command): (org-agenda-fit-window-to-buffer): (org-agenda-prepare-window): (org-agenda-switch-to): * lisp/org-capture.el (org-capture-place-template): * lisp/org-goto.el (org-goto-location): * lisp/org-src.el (org-src-switch-to-buffer): * lisp/org.el (org-tree-to-indirect-buffer): (org-fast-todo-selection): (org-add-log-note): (org-fast-tag-selection): (org-submit-bug-report): * lisp/ox.el (org-export--dispatch-ui): Get rid of calling `delete-other-windows' manually. Instead, make use of `org-display-buffer-slip' + `pop-to-buffer'/`display-buffer'. This way, user overrides in `display-buffer-alist' are honored. * lisp/org-plot.el (org-plot/gnuplot): * lisp/org.el (org-offer-links-in-entry): When `delete-other-windows' cannot be avoided, make it ignore errors in the frames where displaying a lone window is forbidden.

\(a list of strings) as the cdr.

- :check-ind-type - Whether the types of ind values should be checked.

- :plot-str - the formula string passed to :plot-func as PLOT-STR
|
|
Accepts string. Default value: \"'%s' using %s%d%s with %s title '%s'\"

- :data-dump - Function to dump the table to a datafile for ease of
