Similarly, as will be detailed in this section, the bahaviour of the keyboard changes so as to allow for the rapid typing of mathematical symbols. For instance, typing > inserts the arrow >. Starting with version 1.0.7.10, also incorporates several features for the ``semantic'' editing of mathematical formulas, which will be described at the end of this section. When used appropriately, this allows you to write documents in which all formulas are at least correct from a syntactical point of view. A ``syntax corrector'' is included to assist you with this task. Documents with more semantics are for instance useful when using formulas as inputs for a computer algebra system. Such documents are also less likely to contain ``typos''. Other interesting features, such as semantic search and replace, should be developed in the feature. <\traverse> \<#6587\>\<#6863\>\<#4E2D\>\<#8F93\>\<#5165\>\<#6570\>\<#5B66\>\<#516C\>\<#5F0F\>|keyboard/man-enter-math.zh.tm> \<#5B66\>\<#7B26\>\<#53F7\>|keyboard/man-symbols.zh.tm> \<#8981\>\<#6570\>\<#5B66\>\<#7ED3\>\<#6784\>|keyboard/man-main.zh.tm> \<#578B\>\<#5206\>\<#9694\>\<#7B26\>|keyboard/man-large.zh.tm> \<#578B\>\<#7B97\>\<#7B26\>|keyboard/man-big.zh.tm> <\initial> <\collection>
