If, while having a selected text on the screen, you press Ctrl F8, the program will start analyzing all the words in the selection. Incorrect spellings or words not contained in the dictionary, such as proper nouns, will be highlighted, and automatically marked by a special sign (ASCII code 17) for future corrections.
A preliminary version of syntax analysis for Russian, operating only on simple sentences, is included starting with version 1.0.7. Pressing Ctrl Shift F9 delineates a sentence and tries to build its syntactic dependency tree. This function is still rather raw and may hang the system: please use it with caution.
