Today I released the new version, 1.61. You can download it from the homepage.

News regarding keyboard handling:

  • The behaviour of the Enter key is redefined. The most important difference is that the Enter key will not end the keyboard-entry mode any more. Instead it will start a new equation just below the current one. To exit the keyboard entry mode you should use the Esc key or the right-mouse click…. This changed behaviour could annoy some existing users. Sorry.
  • However, text boxes are exception – the Enter key will not start a new text box but will insert new line of text. You don’t have to use SHIFT+Enter any more for that purpose.
  • The behaviour of the ‘ character (single quotation mark) is now redefined. As a result, derived functions in form like g'()  or G”() are now possible.
  • If you hit any of the  ‘(‘, ‘[‘ or ‘{‘ keys as the first and only thing inside the function argument box, you will enable parentheses around the argument box.
  • Commands in form \funcname are now possible to enter functions of the given name. Examples: \funcsum – creates function sum(), \funcg – creates function g(), \funcGamma – creates function represented by capital greek symbol gamma.
  • Commands in form \unitname are now possible to enter measurement units of the given name. Example: \unitpesos – creates measurement unit called pesos.
  • Functions can now be represented by greek symbols. Just enter the command like: \greek_symbol (enter the greek_symbols using  ALT+letter keystroke)
  • function index can now be created/edited by hitting the underline ‘_’ key when the cursor is positioned at the first position inside the function argument. In similar way, you can now power the function (use ALT+number, or the ‘^’ key from the first position inside the function argument)
  • you can now exit function argument by hitting the ‘)’ key (or the ‘]’ key, or the ‘}’ key).
  • function names are now displayed in a dark green color.
  • Some new commands are added: \e, \i, \j – to insert Euler’s number and imaginary units; \d, \par, \partial, \dx, \dy, \dz, \dt – to insert differentials; \dd, \ddx, \ddy, \ddz, \ddt – to add derivations; \dB, \ppm – new units
  • The Enter key can now be used to execute a command (in addition to space bar).
  • You can now enter variables that end with an asterisk symbol, like x* – to enter the asterisk, use the ^* sequence.
  • key sequences: ‘+-‘, ‘-+’, ‘->’ will be converted to plus-minus, minus-plus and right-arrow symbol. Three consecutive dots will be converted to a single triple-dot symbol.
  • The Del or the Backspace keys can now be used to delete empty parentheses, exponents…
  • SHIFT+Enter and SHIFT+Tab keystrokes are now used for matrices exclusively (add row/column). Their behaviour is redefined a bit.
  • You can use SHIFT+BACKSPACE now to move your keyboard cursor ‘just a bit to the left’  – the cursor is nuzzled to the variable just left of it. This is useful if you need to append this variable/number.

News regarding keyboard selections:

  • You can still select expression elements with keyboard, using SHIFT and right/left keyboard arrow keys. However, this feature is now improved a bit. You can use SHIFT+Home, and SHIFT+End to select everything from the cursor to expression beginning/end.
  • You can use CTRL+X, CTRL+C to cut/copy the selection you made with keyboard. Later, you can paste it using CTRL+V.
  • The same is true for matrix rows and columns – you can select them using SHIFT+arrow keys, and then cut/copy/paste them using CTRL+X,C,V keystrokes.
  • The context menu can be open by hitting the Enter key after keyboard selection is made.
  • You can now paste a plain text from windows clipboard into text boxes. You can even paste into equation boxes, but with not-very-defined results.

Other news:

  • The option “Center Parentheses content” is now removed from the menu and is not supported any more
  • As you type an equation, its vertical position is automatically adjusted so that there is no overlap with an equation just above or just below it.
  • There is a new handy way to select/deselect an object – just point your mouse to it and press the ALT+SPACE_BAR keystroke. Even more, if you don’t point your mouse at any object, the ALT+SPACE_BAR will select the last created object. This way you can quickly modify it.
  • The F1 key can now be redefined. Use ‘Options->Keyboard->F1 sets zoom level to 100%’ to redefine it.
  • The LaTeX code can now be generated and copied to windows clipboard. Touch/select an equation and hit the F6 key.

I managed to keep the .exe file under 1MB. However, I am afraid that this is the latest version where this will be possible.
