* Add flag for enabling insert symbols feature * Add symbols overlay directory * Detect if :xy is inserted into editable * Allow naive updating of overlay, and special handling of ':' * First step towards better Virtual Element support * Update floating to reference range on insert text * Position SymbolsOverlay always on top or bottom * Add a data-provider to emulate API * Show correct suggestions in symbols overlay * Rename to replacementLength * Allow replacing via clicking in menu * Optionally remove inline padding of Popover * Hide Symbols overlay on blur of content editable * Add specialKey to inputHandler and generalize how arrow movement is detected - This way macOS users can use Ctrl-N to mean down, etc. * Detect special key from within SymbolsOverlay * Implement full backwards search while typing * Allow navigating symbol menu and accepting with enter * Add some entries to data-provider * Satisfy eslint * Generate symbolsTable from sources * Use other github source, allow multiple names In return, symbol must be unique * Automatically scroll in symbols dropdown * Use from npm packages rather than downloading from URL * Remove console.log * Remove print * Add pointerDown event to input-handler - so that SymbolsOverlay can reset on field click * Make tab do the same as enter * Make font a bit smaller but increase relative icon size * Satisfy type requirement of handlerlist * Revert changing default size of DropdownItems * Remove some now unused code for bootstrap dropdowns
