If you are like me and tend to lean on the line keys, you have have `signal-error-on-buffer-boundary' set to nil (no beeps). However, the pc-select package overrides the definitions of various functions and effectively turns this variable off. For example, `pc-select-move-line-up' calls `next-line'. Next line will only honour the `signal-error-on-buffer-boundary' if called interactively, which it is not from the pc-select functions. My patch changes the calls from: (next-line arg) to: (call-interactively 'next-line arg) If anybody knows a better way, I would love to know. Until then, here is my patch: 2000-02-12 Sean MacLennan <seanm(a)storm.ca&gt; * pc-select.el The following now use `call-interactively': (pc-select-move|mark-line-up) (pc-select-move|mark-line-down) (pc-select-move|mark-page-up) (pc-select-move|mark-page-down) --- xemacs/packages/lisp/pc/pc-select.el.orig Mon Mar 29 22:59:15 1999 +++ xemacs/packages/lisp/pc/pc-select.el Mon Mar 29 23:01:00 1999 ＠＠ -211,7 +211,7 ＠＠ (interactive "p") (setq zmacs-region-stays pc-select-keep-regions) (setq this-command 'previous-line) - (next-line (- arg))) + (call-interactively 'previous-line arg)) (defun pc-select-move-line-down (&optional arg) "Move point down ARG lines, deselecting any marked region. ＠＠ -219,7 +219,7 ＠＠ (interactive "p") (setq zmacs-region-stays pc-select-keep-regions) (setq this-command 'next-line) - (next-line arg)) + (call-interactively 'next-line arg)) (defun pc-select-move-bol (&optional arg) "Move point to the beginning of the line, deselecting any marked region. ＠＠ -247,7 +247,7 ＠＠ (interactive "P") (setq zmacs-region-stays pc-select-keep-regions) (setq this-command 'scroll-down) - (scroll-down arg)) + (call-interactively 'scroll-down-command arg)) (defun pc-select-move-page-down (&optional arg) "Scroll text of current window up ARG lines, deselecting any marked region. ＠＠ -257,7 +257,7 ＠＠ (interactive "P") (setq zmacs-region-stays pc-select-keep-regions) (setq this-command 'scroll-up) - (scroll-up arg)) + (call-interactively 'scroll-up-command arg)) (defun pc-select-move-bob (&optional arg) "Move point to the beginning of buffer, deselecting any active region. ＠＠ -321,7 +321,7 ＠＠ (interactive "p") (pc-select-ensure-mark) (setq this-command 'previous-line) - (next-line (- arg))) + (call-interactively 'previous-line arg)) (defun pc-select-mark-line-down (&optional arg) "Move point down and select ARG lines. ＠＠ -329,7 +329,7 ＠＠ (interactive "p") (pc-select-ensure-mark) (setq this-command 'next-line) - (next-line arg)) + (call-interactively 'next-line arg)) (defun pc-select-mark-to-bol (&optional arg) "Move point and mark to the beginning of the line. ＠＠ -357,7 +357,7 ＠＠ (interactive "P") (pc-select-ensure-mark) (setq this-command 'scroll-down) - (scroll-down arg)) + (call-interactively 'scroll-down arg)) (defun pc-select-mark-page-down (&optional arg) "Scroll text of current window up and mark ARG lines. ＠＠ -367,7 +367,7 ＠＠ (interactive "P") (pc-select-ensure-mark) (setq this-command 'scroll-up) - (scroll-up arg)) + (call-interactively 'scroll-up arg)) (defun pc-select-mark-to-bob (&optional arg) "Move point and mark to the beginning of buffer. --
