1. How can I add a vertical line between Matrix columns? For Horizantal lines I use \cline{from-to} which works fine. But I haven't found the command to do the same for vertical lines.
2. How can I change Matrix size / alignment after I created it and put values in it? Tried to change values in the Math Panel and "Apply"... doesn't work (and adds unwanted spaces). 3. Is there a way to combine matrix squares? (like in Tabulars) 4. How do I fix/use the, probably, bug with Multi-line equations when I mistakely delete the 3rd Square and it becomes only 2? 5. Is there a shortcut to insert delimeters? (opening math panel, pressing on delim button and apply sure does take lotsa time) 6. Is there an easy way to insert a well aligned matrix for "Long Fractions"? example 123 ---------| 3454| 52 32 ---- 25 35 .. .. . .(and so on) 7. What's the correct way to insert Hexadecimal digits? (i've been using m-c r and the letter so it'll be straight) 8. What's the shortcut/place to insert a Field letter like N,Z,Q,R,C that will look like the written letter and not like just a big letter? Thanks!
