28 | ;; This package is for setting "bookmarks" in files. A bookmark | |
29 | ;; associates a string with a location in a certain file. Thus, you | |
30 | ;; can navigate your way to that location by providing the string. | |
31 | ;; See the "User Variables" section for customizations. | |

33 | ;; Thanks to David Bremner <bremner@cs.sfu.ca> for thinking of and | |
34 | ;; then implementing the bookmark-current-bookmark idea. He even | |
d23e2c3f | 35 | ;; sent *patches*, bless his soul... |

40 | ;; Thanks go to Andrew V. Klein <avk@cig.mot.com> for the code that |
41 | ;; sorts the alist before presenting it to the user (in bookmark-bmenu-list | |
d23e2c3f KF |
42 | ;; and the menu-bar). |
43 | ||
d22d6453 RS |
44 | ;; And much thanks to David Hughes <djh@harston.cv.com> for many small |
45 | ;; suggestions and the code to implement them (like | |
e3437989 | 46 | ;; bookmark-bmenu-check-position, and some of the Lucid compatibility |
d22d6453 RS |
47 | ;; stuff). |
48 | ||
60d0378e | 49 | ;; Kudos (whatever they are) go to Jim Blandy <jimb@red-bean.com> |
d23e2c3f KF |
50 | ;; for his eminently sensible suggestion to separate bookmark-jump |
51 | ;; into bookmark-jump and bookmark-jump-noselect, which made many | |
52 | ;; other things cleaner as well. | |

54 | ;; Thanks to Roland McGrath for encouragement and help with defining |
55 | ;; autoloads on the menu-bar. | |

d23e2c3f KF |
58 | ;; values in bookmark-jump and bookmark-set. Everybody please keep |
59 | ;; all the keystrokes they save thereby and send them to him at the | |
60 | ;; end of each year :-) (No, seriously, thanks Jonathan!) | |
