The new v1.81 beta2 is available here: http://www1.datafilehost.com/d/230eed20
This is a more mature beta and I am intending to make an official release soon because the new school year already started in many countries worldwide.
Here is the list of news compared to the official v1.8:
- It is possible to enter functions that do not have argument box. After you enter a function, just hit the Enter key while the argument box is still empty – the box will be deleted… Note: if you hit the ‘(‘ key behind a function that does not have an argument box, the argument box will be created again.
- In the derivation notation (like d/dx) that you cast with the \dd or \parpar commands, it is now possible to generate index to the upper differential sign – using the underline key (example: \dd<underline>)
- The new arrow element is implemented – the arrow with an expression box above it. There is no command to enter this arrow – I need an idea to name this command. At the moment you can enter this arrow it by choosing it from the toolbox.
- Two new types of parentheses are added | > and < |. You can enter them by using \ket and \bra command or by entering sequences [> and <].
- The upper limit box for summation, product and integral signs is no longer visible if you leave it empty – that is, if you only fill in the lower limit box.
- Representation of exponents (powers) is now very much different – there is no insertion point in the front of the base expression box any more. As a result, the exponents are much simpler to enter, but could be somewhat harder to edit.
- There are two new mighty-dot conversion commands: int. and sum. This way you can generate the integral and the summation signs in somewhat faster way than using \int and \sum commands. Also, signs generated by the mighty-dot method will not have upper and lower limit boxes, but you can create them if you press the underline key immediately.
- The method to type differentials is now much changed. The differential can only contain one variable (like dx) unless you type the parentheses first (like d(x+by) ). This way differentials are much easier to type.
- If a variable has an index, the backspace key now enters into the variable index first (to delete elements from the index) before it deletes the variable
- Selected objects are now displayed with some background blue hue.
- The Moving Dot gets somewhat larger as you increase zoom level.
I also made some debugging in hope that the new version will be much more stable. I would love to hear from you… One more question for creative readers: How could I use the Insert key? Also, double comma (,,) strokes?
