All instruments are represented hierarchically in a tree structure in which the instrument types act as root elements: Cash, Futures, Stocks etc.
The tree has a dynamic instrument search function that works instantaneously: you only need to type in a few letters from the name of the instrument you are looking for.
You can drag an instrument from the tree to other modules by left-clicking the instrument and holding down the left mouse button. For example, you can drag it to a chart in order to view the history of price changes. Otherwise, you can double-click on the name of the instrument and evoke the default action you have set for it in the settings (by default, it evokes opening the instrument chart.)
You can hide a certain type of instruments in the tree by clicking the correspondingly coloured icon under the search window. Instruments of this type will be also excluded from the search scope.
Jump to the instruments tree by pressing Ctrl+i buttons on your keyboard. Navigate inside the module with arrows and the Tab button. To evoke the default action, press Enter after finding the instrument you need.
