help-on-command-completion-error « 1
Controls the help window. If non-zero, Emacs will print a list of possibilities when an ambiguous entity (command, variable, database search-list and so on) is given. Otherwise, Emacs will just ring the bell and wait for you to type more.
Controls the way Emacs displays regions. When set, the region is displayed with graphic rendition defined by the variable highlight-region-graphic-rendition. By default, the region is bolded. If mark is not set, the buffer is displayed normally.
highlight-region-graphic-rendition « 1
Controls the way that the highlighted region is displayed. It is the string of graphic rendition characters which are part of the ANSI SGR sequence.
On VT200 series terminals and terminal emulators, the following renditions are possible:
- 1 -- bold
- 4 -- underscore
- 5 -- blinking
- 7 -- reverse video.
These renditions can be combined by separating each rendition with a ;.
If automatic-horizontal-scrolling is 1 the value of horizontal-scroll-step is used.
horizontal-scroll-step controls how far Emacs will move the window horizontally to ensure that dot is visible.
Set horizontal-scroll-step to the number of columns that emacs will ensure is between dot and the edge of the window.
