This page is about library modeline-char.el, which shows, in the mode-line, the character after point and its Unicode code point.
Minor mode ‘mlc-char-in-mode-line-mode’ toggles this on/off for the current buffer, and global minor mode ‘mlc-char-in-mode-line-mode-global’ does the same globally, i.e., for all buffers.
You can customize faces ‘mlc-mode-line-char-format’ and ‘mlc-mode-line-char-format-code’, which are used for the character and its code point, respectively.
Click the mouse on the mode-line character info:
‘mouse-1’: Show more info about the character (same as `C-u C-x =’ info).‘mouse-2’: Copy the character as the secondary selection, so you can yank it anytime, until you redefine the secondary selection again.‘mouse-3’: Show the character enlarged, as a tooltip.
