TkInfo: a free browser for info files

Features of tkInfo include:

• Intuitive point-and-click interface.
• Supports index lookups (for info files which contain an index).
• File-wide search (exact or regular expression).
• Multiple windows.
• "Redirect window feature" (bound to right mouse button) allows easy exploring of large menus.
• Repeatedly hitting Space will scroll through the whole info file in logical order.
• Can be operated with little mouse movement: important commands bound to right button, scrolling with middle button, selecting with left button.
• Quick mouse-less operation: Tab jumps from link to link, Return selects, key bindings almost identical to the ones of the standard info program and emacs' info mode.
• History list of visited info nodes.
• Can be embedded into other Tcl/Tk programs to provide on-line help.
• Deals with compressed info files.

Relevant information and links to other software

• The Texinfo Home page, contains documentation and gives a link to download the main piece of software, texi2any, also known as makeinfo, which can be used to convcert texinfo sources into a wide variety of formats.
• The editor Emacs at https://www.gnu.org/software/emacs/ includes an info reader which allows for key-based or mouse-based operation. Newer versions of the editor contain a cool feature, the "speedbar", which provides a nice navigatable tree view of info files. Emacs runs on Unix, MacOS and Windows.
• XEmacs, a variant of Emacs available from http://www.xemacs.org/, includes the most powerful info reader to date; it supports bookmarks, annotations, incremental search and index lookups. It is more user friendly than the emacs info mode but still not too intuitive to use. Once you've read the available help text you'll love it though. Xemacs is huge and runs, contrary to what its name might suggest, on Unix, Windows and Macs.
• OO-Browser is a powerful class browser and editor for object oriented languages. It comes with the editor XEmacs and includes a separate X-based program (xoobr) for tree views and stuff. OO-Browser can also be used as an innovative object-oriented info browser.
• TkMan, a very comfortable man page reader available from https://sourceforge.net/projects/tkman/, includes a texinfo viewer. TkMan's formatting of info nodes looks much better than that of an ordinary info reader (such as tkInfo) and it also provides a nice tree based view of the file structure; however, it needs the texinfo sources of the documentation, not the info files. It uses Tcl/Tk and runs on Unix.
• Pinfo is a Unix text-mode browser for info files and man pages which is more intuitive than the original GNU info browser and works very much like the text-mode web browser lynx. It is available from https://github.com/baszoetekouw/pinfo and is included in most Linux distributions.
• Pdftex can produce PDF files from texinfo input. This produces nice, searchable, cross-linked files with indexes and tables of contents which can be printed or viewed with any PDF reader. Pdftex can be gotten from http://ctan.tug.org/tex-archive/systems/pdftex/
• The file manager and web browser Konqueror is part of the Unix KDE desktop/GUI and can be used to view man pages, info pages, and KDE help pages. It can be gotten from the KDE homepage.
• Yelp is an integrated help browser for the Gnome desktop/GUI which displays HTML documents, man pages and info files. It can be gotten from the GNOME homepage. GNOME is designed for Unix.
