PyCoCuMa has many tool-tips (help balloons); e.g. leave the mouse cursor \
over an address-type button in 'Edit Contact' to get the meaning of the \
small symbolic images.
Double-click on a row in List View to switch to Card View.
Double-click on the card in Card View to open the contact for edit.
Double-click on a free day of the Calendar to create a new journal entry for this date.
Enter the first characters of a family name into the \
'Search/Select' textbox on the top to get a list of contacts starting with \
this family name.
To *add a category*, simply add the category to the comma-separated list \
in the 'Categories' textbox of a contact. After saving the card, the \
category will appear in the 'Filter' combobox.
To *change the sorting order* of a contact, edit the 'Sort-String' field \
provided by the 'Additional Fields..' dialog. E.g. a contact named \
'Niklas van Haarten' will be found under the letter 'v' at first; \
but by setting 'Sort-String' to 'Haarten' you can then move the card to the \
letter 'H', were you would probably expect it to be.
Install MikTeX for Windows (""")

environment variable in order to use 'File'->'Page View' on Windows.
Edit the variables 'url_viewer' and 'mailto_program' in '~/.pycocuma' to set \
them to your preferred web browser and mail-composer application. \
If you leave 'url_viewer' blank, PyCoCuMa will try to use your platform \
specific default web browser.
