I think it's the same font that used on old FreeBSD versions, before the current font being used.
The man page is too long, how could I search for it? Is there any tool to help me to search for a specific term in the man page? Searching manually seems not to be an option.
The man page are listed using a pager with is less(1). When the man page is open you have a colon : in the lowest row. If you press the slash
/ followed by font the display will jump to the next position where the text font appears. The you can use the n key to jump to the next location or the N key to go back. Now you have the next man page to read. Fortunately one needs only a small subset of all keys 
.
foreach y (8 14 16)
foreach? sysrc -e font8x$y
foreach? end
font8x8="gallant"
font8x14="gallant"
font8x16="gallant" sysrc font8x$y=gallant in the loop. You can see a list of all fonts and set them as root from a console with vidfont(1).To read man pages comfortably, you can use a graphical tool e.g. sysutils/khelpcenter or type
man:rc.conf in the address line of x11-fm/konqueror pkg install kde5 octopkg falkonRight click on the start menu -> edit menu entries -> select System/OctoPkg -> run as user: root pkg install asr-manpagesThanks. But I will not install the entire kde5 just to read a man page.
Very likely other GUIs have graphical help systems, too. Unfortunately, AFAIK there is no easy text-mode man(1) pager; i.e. without not-so-intuitive commands like more(1) & less(1). To search in these (default man pagers), use the slash ("/"). When you have used that a few times, you'll get used to it. It's UNIXish, and you choosed FreeBSD which is a UNIXoid. Maybe you find sysutils/most (a text mode pager like more/less) easier to use (e.g. S to search).
It is likely you already have
xman installed. It is part of the standard Xorg distribution afaik.Same. To me it also has a few similarities to the OpenBSD default terminal font, spleen (https://github.com/fcambus/spleen) in that the glyphs appear fairly square.
Yes, or install editors/emacs. Not only it's a complete IDE, it can also read & send e-mail, cook coffee, etcetera, for shure it can format man pages, too! It's an own whole galaxy:The nerdy way is to install devel/plan9port and start theacmeeditor. [...]
The only text editor you'll ever needYou can even start an ssh session in the editor!
portfind -r emacs: Results: 372 / Matches: 372 Nowadays, the GUIs usually do not depend on a full X11 installation (x11/xorg), but either install only those components they need, or the stripped-down x11/xorg-minimal. No xdm, xterm, xrdb, xmodmap, xman etc.pp.
I always install the full xorg.
True, but people have always been able to install butchered versions of Xorg. That is why I explicitly used the word "standard". The minimal xorg package is definitely useful for "Point of Sale" units however. We use it for our arcade units (with a few additional removals).
You know something is wrong with a language when a "minimal" meta-package drags in 3 versions of it.
python27
python35
python37Excuse me please but I checked on both freshports and
pkg install xorg-minimal on my system but didn't see it drags in 3 versions of python at all. It could be because my system already has the standard xorg installed, though.
