completion for \<^const>, although it often requires an extra argument;

document markers are formal comments, and may thus occur anywhere in the command-span;

use "Isabelle DejaVu" fonts uniformly: Text Area, GUI elements, HTML output etc.;

support for completion;

support for completion;

added \<^cancel> operator for unused text;

more completion templates;

more robust hyphen (see also "Soft hyphen (SHY) – a hard problem?" http://jkorpela.fi/shy.html);

more symbols;

added glyph from "Deja Vu Sans Mono" font;

some icons from Symbola font;

symbol interpretation for \<circle>;

clarified;

discontinued irregular abbrevs: ".o" counts as word, "+o", "*o", "-o" are occasionally used as ASCII notation, "*o" is in conflict with "(*o" in comments;

\<struct> loses its rendering and is superseded by \<diamondop>;
tuned;

clarified abbrev;

clarified groups, notably for Symbols dockable;

glyphs for \<bind>, \<then>;

simplified abbrevs: exploit ambiguity;

more arrow symbols;

more arrow symbols;

support short form for \<^theory_text>;

added @{undefined} with somewhat undefined symbol;

retain traditional rendering of \<paragraph>;

IsabelleText for unusual symbol;

symbolic syntax "\<comment> text";

document antiquotation @{footnote};
render \<^footnote> as pilcrow -- the rarely used \<paragraph> loses its interpretation;

rendering for \<^verbatim>;

clarified control antiquotations: decode control symbol to get name;
document antiquotations @{emph}, @{bold};
symbol interpretation for \<^emph>;
tuned;

unused -- avoid confusion in Symbols dockable;

clarified control symbols;

some control symbols for markup and formatting;

added symbol for \<hole> (from DejaVuSansMono and DejaVuSansMono-Bold version 2.34);

receovered alternative abbrevs for \<open> \<close> from 8e8243975860, to accommodate national keyboard layouts where "`" might be hard to produce;

clarified abbreviations for cartouche delimiters, to work in any context;

removed abbrev "<-" again (see c771f0fe28d1) due to conflict with important "<->" and "<-->";

more symbol abbrevs, e.g. relevant for list comprehension in HOL/List.thy or HOL/Library/Monad_Syntax.thy;

more symbol abbrevs to support HOL library maintenance;

always show PIDE positions as \<here> (0x002302 "House" from DejaVuSansMono);

group symbols;

support for nested text cartouches;
clarified Symbol.is_symbolic: exclude \<open> and \<close>;

added \<newline> symbol, which is used for char/string literals in HOL;

uniform abbrevs for left/right arrows;

more abbrevs according to Isabelle/HOL ASCII replacement syntax;

added common alternative for == (its ambiguity also avoids conflict with ==>);
clarified (= )= [= ]= (like <= >=);
removed * (too intrusive);

single-letter abbrev does not make sense -- too many candidates;

fewer conflicts -- adhoc resolution of == vs. ==> via unicode (!) image;

more symbol abbrevs;

misc tuning -- reduce conflicts;

more symbol abbrevs, based on ProofGeneral-4.2/isar/isar-unicode-tokens.el and traditional Isabelle/HOL ASCII replacement syntax;

complete symbols only in backslash forms -- less intrusive editing, greater chance of finding escape sequence in text;
complete words >= 3 characters only;
discontinued short word abbrev "Un" (see also fdd6e68e29d9 and e38e80686ce5);

discontinued rendering of obsolete \<onesuperior>, \<twosuperior>, \<threesuperior>;

discontinued redundant abbreviations -- Isabelle/jEdit provides keyboard shortcuts already;

discontinued special treatment of \<^isub> and \<^isup> in rendering or editor front-end;
document antiquotations: renamed term style "isub" to "sub";

more robust font for control symbols, to ensure these obscure codepoints are properly rendered;

tuned symbol groups;

tuned symbol groups;

clarified symbol groups, despite this traditional arrangement in X-symbol grid;

some grouping of Isabelle symbols, based on X-Symbol grid in PG-3.7.1.1 and a proposal by Fabian Immler;

prefer calligrapic \<RR> \<II> over \<Re> \<Im> for "screen" display (NB: official unicode defines only one version of these glyphs, unlike TeX);

discontinued default rendering for Oheimb's double-space;

some arrow symbols from DejaVuSansMono for bsub/esub/bsup/esup;

removed obsolete font specification;

abbreviations for special control symbols;

some unicode chars for special control symbols;

more symbol abbrevs;

avoid clash of \<upharpoonright> vs. \<restriction> (cf. 666ea7e62384 and 3c49dbece0a8);

tuned abbrevs for long arrows, according to usual ASCII syntax;

removed slightly exotic symbol abbreviations for now -- achieves a coherent (unique) mapping;
(NB: in principle symbol abbreviations could well be ambigous);

Fix a duplicate abbreviation || in etc/symbols.

tuned abbrevs;

fixed abbrev !! for \<And>;

removed Ids;

activated \<A>, \<a>, \<AA>, \<aa>;
disabled \<RR>, \<II> which overlap with codepoints for \<Re>, \<Im>, remapped to unofficial place within Isabelle font;

tuned abbrevs;

added some abbrevs;
\<euro>: from default font;

removed redundant "symbol" property;
added "font" propery;
disabled alternative letters (\<A> etc.) for now;

Default interpretation of some Isabelle symbols.
