102 <h1 class="Sh" id="UI_CONCEPTS"><a class="permalink" href="#UI_CONCEPTS">UI
104 <p class="Pp"><code class="Nm">telescope</code> interface is divided into four
105 areas: the tabline, the body, the modeline and the echoarea/minibuffer.</p>
106 <p class="Pp">The tabline is always at the top of the screen and displays the
107 tabs separated by a vertical line. When there are more tabs than the size of
108 the window allow to display, the characters ‘<’ or
109 ‘>’ are shown at the start/end of the tabline to indicate
110 that there are more tabs in that direction.</p>
111 <p class="Pp">The body occupies the majority of the visible area. It contains
112 the current page and optionally a side window.</p>
113 <p class="Pp">The modeline is the second to last row of the screen. It shows
114 some information about the page: a spinner when the page is loading, the
115 trust level, the document type, the scroll offset and the URL.</p>
116 <p class="Pp">The echoarea is usually the last line of the screen. Messages are
117 often showed there, and link addresses too. The echoarea is also used to
118 obtain input from the user. When commands like
119 <code class="Ic">swiper</code> or <code class="Ic">link-select</code> are
120 invoked, the minibuffer area grows to show possible completions.</p>
123 <h1 class="Sh" id="TOFU"><a class="permalink" href="#TOFU">TOFU</a></h1>
124 <p class="Pp"><code class="Nm">telescope</code> aims to use the “Trust,
125 but Verify (where appropriate)” approach for TOFU (“Trust On
126 First Use”). The idea is to define three level of verification for a
130 <dd>(‘!’) the server fingerprint does NOT match the stored
133 <dd>(‘v’) the server fingerprint matches the store one.</dd>
135 <dd>(‘V’) the fingerprint matches and has been verified
138 <p class="Pp">The trust level of the page is indicated in the modeline with the
139 indicated character.</p>
140 <p class="Pp">Most of the time the “trusted” level is enough, but
141 where is appropriate users should be able to verify out-of-band the
143 <p class="Pp">At the moment, there is no built-in support for an out-of-band
144 verification though.</p>
147 <h1 class="Sh" id="SUPPORTED_PROTOCOLS"><a class="permalink" href="#SUPPORTED_PROTOCOLS">SUPPORTED
149 <p class="Pp">The following protocols are supported:</p>
152 <dd>About pages are <code class="Nm">telescope</code> internal page. See
153 about:about for a list of all these pages.</dd>
155 <dd>File types know to <code class="Nm">telescope</code>, such as .gmi,
156 .gemini, .txt, .md, .markdown, .diff or .patch, can be viewed inside the
157 application. Types of local files are detected solely based on the file
158 extension. On some systems, such as <span class="Ux">OpenBSD</span>, only
159 files inside special directories (like <span class="Pa">/tmp</span>
160 <span class="No">or</span> <span class="Pa">~/Downloads</span>) are
163 <dd>Finger URLs are interpreted as follows:
164 <ul class="Bl-bullet Bl-compact">
165 <li>the host is determined by the host name portion of the URL</li>
166 <li>if the user portion of the URL is provided, it's interpreted as the
167 user to finger, otherwise the path component will be used</li>
169 thus <a class="Lk" href="finger://user@hostname">finger://user@hostname</a>
170 and <a class="Lk" href="finger://hostname/user">finger://hostname/user</a>
171 are treated as the same URL.</dd>
173 <dd>Gemini is fully supported, with the exception of client-certificates.</dd>
175 <dd>Gopher support is limited to items type 0, 1 and 7. All text is assumed to
176 be encoded in UTF-8 (or ASCII).</dd>
178 <p class="Pp">User-entered URLs, given as argument on the command line or
179 entered with <code class="Ic">load-url</code>, are intepreted with a simple
181 <ul class="Bl-bullet Bl-compact">
182 <li>if it's a proper absolute URL then use it as-is,</li>
183 <li>if it starts with “./” or “/” assume it's a
185 <li>otherwise assume it's a Gemini URL.</li>
189 <h1 class="Sh" id="CONFIGURATION_FILE"><a class="permalink" href="#CONFIGURATION_FILE">CONFIGURATION
191 <p class="Pp">During the startup, <code class="Nm">telescope</code> reads the
192 configuration file at <span class="Pa">~/.config/telescope/config</span> or
193 <span class="Pa">~/.telescope/config</span>.</p>
194 <p class="Pp">It's possible to load a custom configuration file using the
195 <code class="Fl">-c</code> flag.</p>
196 <p class="Pp"><code class="Nm">telescope</code> will also load a file called
197 <span class="Pa">config-TERM</span>, where “TERM” is the name
198 of the terminal type (i.e. the TERM environment variable), if it exists.</p>
199 <p class="Pp">The format of the configuration file is fairly flexible. The
200 current line can be extended over multiple ones using a backslash
201 (‘\’). Comments can be put anywhere in the file using a hash
202 mark (‘#’), and extend to the end of the current line, but
203 backslashes can't be used to extend comments over multiple lines.</p>
204 <p class="Pp">The following constructs are available:</p>

390 Control-x, M-x means Meta-x, where the Meta key may be either a special key
