Can you highlight by word, line and regexp?
Highlighting by Word, Line and Regexp. With Emacs’s Hi-Lock mode you can highlight by word, line or regular expression with ease. The highlighter functionality in Emacs is particularly helpful when if you are trying to do complex code refactoring or if you are fixing data or text by hand.
Is the accepted answer the correct answer to my regexp problem?
The accepted answer is the correct answer to my regexp problem, so I left it there. But to solve my own problem, I found a way to do it: instead of trying to negate specific string in the regexp in my original entry added to display-buffer-alist to handle Helm buffers, just add another entry for the case you are trying to exclude.
How does highlighting work in Emacs with Elisp?
There is a mechanism for storing and restoring the Hi-Locks you’ve created. If you create highlights interactively you can tell Emacs to insert those patterns into the active buffer by running M-s h w. Emacs will wrap the elisp patterns in the comment format used by the buffer (if one is defined) or ask if you no comment format is defined.
Why do I need a regexp for helm?
For example, I want to create a regexp that accepts a set of strings with *.*helm.** except a few ones such as *helm help*. It means, *helm help* should be excluded. I want this regexp functionality because I set display-buffer-alist to position Helm windows where I like it to be:
Which is the best way to read tooltips?
Users generally look where they click (or hover). However, since tooltips lack, a moderate contrast is important to ensure users see the text in the tooltip. Additionally, for users with visual impairments, a white page with light-grey tooltips is especially difficult to read.
Do you need tooltips for unlabeled icons?
Provide tooltips for unlabeled icons. Most icons have some level of ambiguity, which is why we recommend text labels for all icons. If you’re too stubborn to provide text labels for the icons on your site, the least you can do is provide your users with a descriptive tooltip.
Why are tooltips not good for your website?
Tooltips with obvious or redundant text are not beneficial to users. If you can’t think of particularly helpful content, don’t offer a tooltip. Otherwise, you’ll just add information pollution to your UI and waste the time of any users unlucky enough to activate that tooltip.
