In any of the assets you can use the keyboard to carry out certain functions without needing to use the mouse.
So:
You can move between the columns by pressing <Tab> on the keyboard.
Within each column's dropdown list you can open the list using the right or down arrow keys, you can navigate through the list using the up and down arrow keys, you can open sub menus using the right arrow key, etc.
In the IR asset in any of the fields you can type in the value you want to display. You can also partially type in the value you want, and the system will display the first value in the dropdown list that matches what you have typed. So if in the Parameter column you type swapt and then press <Enter> or <Tab> the system displays "Swaption Implied Vol"; similarly, if in one of the date columns you enter 1y you will get 1 year, etc. For the parameters where you define both an expiry and a swap duration (i.e., the Swaption Implied Vol, Swaption Collar and Swaption Strangle parameters) you can enter the standard SD shortcuts in the Expiry field. So if you enter 18m2y and then press <Enter> or <Tab> the system will assign 18 months to the Expiry field and two years to the swap duration.
In the CM asset the autocomplete functionality is supported to define both the underlying and the parameter. That is, when you type in the underlying or parameter’s name the system automatically displays the supported options for you according to the letters you have typed (this includes any sub menus in the Underlying list).
You can also define an underlying and parameter solely using your keyboard. You can open the list using the right or down arrow keys, you can navigate through the list using the up and down arrow keys, you can open sub menus using the right arrow key, etc.
