52 7ee780fa 2021-07-21 op .Sh UI CONCEPTS
54 7ee780fa 2021-07-21 op interface is divided into four areas: the tabline, the body, the
55 7ee780fa 2021-07-21 op modeline and the echoarea/minibuffer.
57 7ee780fa 2021-07-21 op The tabline is always at the top of the screen and displays the tabs
58 7ee780fa 2021-07-21 op separated by a vertical line.
59 7ee780fa 2021-07-21 op When there are more tabs than the size of the window allow to display,
60 7ee780fa 2021-07-21 op the characters
64 7ee780fa 2021-07-21 op are shown at the start/end of the tabline to indicate that there are
65 7ee780fa 2021-07-21 op more tabs in that direction.
67 7ee780fa 2021-07-21 op The body occupies the majority of the visible area.
68 7ee780fa 2021-07-21 op It contains the current page and optionally a side window.
70 7ee780fa 2021-07-21 op The modeline is the second to last row of the screen.
71 7ee780fa 2021-07-21 op It shows some information about the page: a spinner when the page is
72 7ee780fa 2021-07-21 op loading, the trust level, the document type, the scroll offset and the
75 7ee780fa 2021-07-21 op The echoarea is usually the last line of the screen.
76 7ee780fa 2021-07-21 op Messages are often showed there, and link addresses too.
77 7ee780fa 2021-07-21 op The echoarea is also used to obtain input from the user.
78 7ee780fa 2021-07-21 op When commands like
81 7ee780fa 2021-07-21 op .Ic link-select
82 7ee780fa 2021-07-21 op are invoked, the minibuffer area grows to show possible completions
83 7ee780fa 2021-07-21 op and navigate through them.
86 7ee780fa 2021-07-21 op aims to use the
87 7ee780fa 2021-07-21 op .Dq Trust, but Verify Pq where appropriate
90 7ee780fa 2021-07-21 op .Pq Dq Trust On First Use .
91 bba111bc 2021-03-28 op The idea is to define three level of verification for a certificate:
92 bba111bc 2021-03-28 op .Bl -tag -width 12m
95 7ee780fa 2021-07-21 op the server fingerprint does NOT match the stored value.
98 7ee780fa 2021-07-21 op the server fingerprint matches the store one.
101 7ee780fa 2021-07-21 op the fingerprint matches and has been verified out-of-band.
104 7ee780fa 2021-07-21 op The trust level of the page is indicated in the modeline with the
105 7ee780fa 2021-07-21 op indicated character.
107 bba111bc 2021-03-28 op Most of the time the
109 bba111bc 2021-03-28 op level is enough, but where is appropriate users should be able to
110 bba111bc 2021-03-28 op verify out-of-band the certificate.
112 bba111bc 2021-03-28 op At the moment, there is no built-in support for an out-of-band
113 bba111bc 2021-03-28 op verification though.
114 bba111bc 2021-03-28 op .Sh DEFAULT KEY BINDINGS
115 bba111bc 2021-03-28 op The default key bindings are very similar to GNU Emacs, but care has
116 bba111bc 2021-03-28 op been taken to include also bindings familiar for
121 bba111bc 2021-03-28 op In the following examples, C-x means Control-x, M-x means Meta-x,
122 bba111bc 2021-03-28 op where the Meta key may be either a special key on the keyboard or the
123 bba111bc 2021-03-28 op ALT key; otherwise ESC followed by the key X works as well, and C-M-x
124 bba111bc 2021-03-28 op means to press the key X together with both Control and Meta.
126 bba111bc 2021-03-28 op Keys are usually a single character, like
130 bba111bc 2021-03-28 op but some special keys are accepted as well.
