Using keyboard

``TROLIS'' system in all it's interface types has a common keyboard interface (as far as possible). Thus, user can feel comfortable when migrating from one interface type to another. Below are described most commonly used keys and corresponding functions, invoked when pressing them:

• ``ENTER'' - fixation (completion) of information field entry; button with an entry focus (in GUI) activation; launching of various processes.
• ``F4'' (CHUI) or ``Esc'' (GUI) - step back, cancellation of requests, refusal of execution; closing interface windows without fixing changes. Will hereinafter be referred as ``F4/Esc''.
• ``F1'' - help key. Acts with fields, which are logically related to system registries. Shows a popup window with list of corresponding registry valid values. User then may choose suitable value from this list. There is an icon with the sign (``?'') in GUI interface, which is active for the mouse click. The list of valid values also shows when user enters incorrect (impossible) value to the field, related with some registry.
• ``F2'' - is used mainly in the information entry dialogs. Pressing this key completes entering of information from wherever user is in the dialog and closes it. It is equivalent of pressing <OK> button in GUI or entering last field in the form.
• ``F3'' (ÔÏÌØËÏ CHUI) - key for accessing top menu in the booking screen.
• ``TAB'' (CHUI É GUI) - moving between subwindows in the main booking screen. In other windows (GUI only) - moving to the next field entry (equivalent to ``ENTER'' key) as usual for Windows interface.
• ``F7'' - (Recall) - resets field value to the previous entry when mistaken entry is entered. Works only before finishing ``Enter'' key is pressed.
• When user enters information to the field - standard editing keys are available such as ``Insert'', ``Delete'', ``Backspace'', ``Home'' É ``End''.

Following keys and mouse actions are available in various bowsing lists - for example in search results, passenger lists, etc.:

• ``Enter'' or mouse double-click - provides a certain action with current line of browser - for example editing information of the line in separate dialog.
• ``Cursor-Up'', ``Cursor-Down'' - moves one line up or down.
• ``Page-Up'', ``Page-Down'' - moves to the previous/next screen within a browser.
• ``Home'', ``End'' - moves to the beginning/end of the browser.
• Positioning browse selector with the mouse is also possible in GUI interface. And so is for scroll bars to scroll through the entries of the browse. When appropriate value is found - click mouse left button in the desired line for it's selection.
• Not all columns is seen across in some browsers. You can use ``Cursor-Left'' and ``Cursor-Right'' in such cases for navigation through the columns of those browsers. The horizontal scroll bar is also available in this case.
• Some browses has a quick search feature (registry lists, check-in list). You can press first symbol (letter) of the entry for quick reposition to it. If entry doesn't exist or feature doesn't work in that context - nothing will happen.

When working with the booking main screen, and also in some other windows and dialogs - some special key combinations (called ``shortcuts'') are available for the special functions. In the booking screen all special operations (booking saving, ticketing, cancellation, etc.) have it's special shortcut. Usually combination consists of ``Ctrl'' key and one Latin character key and will be pointed to as ``Ctrl-X''. In GUI Most such functions in GUI booking screen are duplicated by icons (activated by mouse-click) on the top of the screen.
