<tmdoc-title|General prefix rules>
|
|
|
|

|
Since there are many keyboard shortcuts, it is important to have some ways
|
|
|
|
|
|
of classifying them in several categories, in order to make it easier to
|
|
|
|
|
|
memorize them. As a general rule, keyboard shortcuts which fall in the same
|
|
|
|
|
|
category are identified by a common prefix. The active prefixes heavily
|
2019-01-16 20:24:24 +08:00
|
|
|
|
depend on the selected \Plook and feel\Q in <menu|Edit|Preferences>. In the
|
2011-08-28 15:59:50 +08:00
|
|
|
|
current look and feel of your <TeXmacs> system,<space|0.4spc>the main
|
|
|
|
|
|
common prefixes are as follows:
|
|
|
|
|
|
|
|
|
|
|
|
<\description>
|
|
|
|
|
|
<item*|<prefix|std>>Standard shortcuts, which are similar to shortcuts
|
|
|
|
|
|
used by other applications (for the selected look and feel). For
|
|
|
|
|
|
instance, <shortcut|(clipboard-paste "primary")> can be used for pasting
|
|
|
|
|
|
text on your system.
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|cmd>><TeXmacs> shortcuts, which often rely on the current
|
|
|
|
|
|
editing mode. For instance, <key|text s> produces <strong|strong> text in
|
|
|
|
|
|
text mode and a square root <math|<sqrt|>> in math mode.
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|altcmd>>Compound <TeXmacs> shortcuts. Usually, these
|
|
|
|
|
|
shortcuts first indicate the kind of markup to which the command will
|
|
|
|
|
|
apply and then specify the specific command. For instance, the
|
2019-01-16 20:24:24 +08:00
|
|
|
|
<key|executable> prefix is used for inserting executable markup, which is
|
2011-08-28 15:59:50 +08:00
|
|
|
|
useful for <hlink|writing style files|../../../devel/style/style.en.tm>.
|
|
|
|
|
|
One example is the shortcut <key|executable +> for the insertion of an
|
|
|
|
|
|
addition.
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|structured:geometry>>This prefix is used in combination
|
|
|
|
|
|
with arrow keys and certain other special keys for <hlink|positioning and
|
|
|
|
|
|
resizing objects|../../editing/man-structured-geometry.en.tm>
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|structured:move>>This prefix is used in combination with
|
|
|
|
|
|
arrow keys and some other special keys for <hlink|structured cursor
|
|
|
|
|
|
movements|../../editing/man-structured-move.en.tm>.
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|special>>This prefix is occasionally used in combination
|
2019-01-16 20:24:24 +08:00
|
|
|
|
with letters and punctuation symbols for creating some additional easy to
|
2011-08-28 15:59:50 +08:00
|
|
|
|
remind shortcuts.
|
|
|
|
|
|
|
|
|
|
|
|
<item*|<prefix|symbol>>This prefix can be used in combination with normal
|
|
|
|
|
|
letters for the insertion of special symbols. For instance,
|
|
|
|
|
|
<key|text:symbol s> yields <20> and <key|math:symbol a> yields
|
|
|
|
|
|
<math|<op|\<amalg\>>>. The <prefix|symbol> prefix is also used for the
|
2019-01-16 20:24:24 +08:00
|
|
|
|
insertion of \Pliteral characters\Q. For instance, <key|symbol \\> will
|
2011-08-28 15:59:50 +08:00
|
|
|
|
always produce the \\ character, whereas the <key|\\> key is used for
|
|
|
|
|
|
entering <hlink|hybrid commands|man-hybrid.en.tm>.

|
|
|
|
|
|
|
Unfortunately, <prefix|altcmd>-based shortcuts are superseded by system
|
|
|
|
|
|
shortcuts on several systems. For instance, accented characters and common
|
|
|
|
|
|
special symbols are entered using this prefix under <name|Mac OS>. In that
|
|
|
|
|
|
case, you may use the <key*|escape> key as an equivalent for <key|altcmd>.
