Bookmark

Emacs bookmarking makes use of three things that are related but different: a bookmark list, a bookmark file, and a bookmark-list display. Understanding these is important to using Emacs bookmarks. They are explained at Bookmark Basics. Some bookmarking commands to get you started:
‘C-x r m’ – set a bookmark at the current location (e.g. in a file)
‘C-x r b’ – jump to a bookmark
‘C-x r l’ – list your bookmarks
‘M-x bookmark-delete’ – delete a bookmark by name
Your personal bookmark file is defined by option ‘bookmark-default-file’, which defaults to ~/.emacs.d/bookmarks in the most recent Emacs versions and to `~/.emacs.bmk’ in older versions. The file is maintained automatically by Emacs as you create, change, and delete bookmarks.
(Bookmark+ makes it easy to have multiple bookmark files – different sets of bookmarks for different uses.)
The bookmark list (buffer ‘Bookmark List’) is like Dired or BufferMenu for bookmarks. You access it using ‘C-x r l’. (Emacs sometimes calls it the “bookmark menu list”, which is a misnomer.)
Some keys in ‘Bookmark List’:
‘a’ – show annotation for the current bookmark
‘A’ – show all annotations for your bookmarks
‘d’ – mark various entries for deletion (‘x’ – to delete them)
‘e’ – edit the annotation for the current bookmark
‘m’ – mark various entries for display and other operations, (‘v’ – to visit)
‘o’ – visit the current bookmark in another window, keeping the bookmark list open
‘C-o’ – switch to the current bookmark in another window
‘r’ – rename the current bookmark
Quick calculate
quick 진법변환 : C-x * q
Quick calc mode : 10#255 ==> 10진수 255에 대한 16,8,2진수 표시
Quick calc mode : 16#ABCD ==> 16진수 0xABCD에 대한 16,8,2진수 표시
Quick calc mode : 16#90000-10#1024 ==> 16진수 0x90000 - 10진수 1K 계산
Result: 589824 - 1024 => 588800 (16#8FC00, 8#2176000, 2#10001111110000000000)
