The chm and PDF readers provided by Ubuntu are not very easy to use, have limited functions, and are very slow. Later, chm changed to chmsee, which is good to use, but does not have the search function. There is nothing to do if you look at common electronic documents, but if you look at documents such as technical manuals, without this, it will be annoying to find a function to use. As for PDF, it was later replaced by Adobe. However, like the performance in Windows, it is not only big but also not easy to use, and it is even worse in Ubuntu. Today I found two good software

Today we found two good software, kchmviewer and Foxit reader.
The former is kde, and there is a command in the source:
Sudo apt-get install kchmviewer
As for the latter, I have been using this in Windows, which is small and powerful. I only know today that the Linux version has been released for a long time and is now version 1.1. Although it has not reached the Windows version level, it is very good and very fast to load, which is particularly useful. Http://www.linuxidc.com/linux/2007-04/1077.htm. After downloading and decompressing the package, double-click to run FoxitReader without installation. If it is easy to use, you need to set it as the default reader. You only need to find a PDF file, right-click it, and select "FoxitReader" in the open mode of the attribute. (Of course, because it is not installed, the default list does not exist. You can find the storage directory as needed ).
