the user interface consists of several kinds of components, some of which benefit from explanation.
## text fields
text fields are able to hold... text.
click on a text field to start editing, and click away to stop editing.
the following keyboard shortcuts work while on a text field:
-`Ctrl-X`: cut
-`Ctrl-C`: copy
-`Ctrl-V`: paste
-`Ctrl-A`: select all
(replace Ctrl with Command on macOS)
## number input fields
these work similar to text fields, but you may only input numbers.
they also usually have two buttons which allow you to increase/decrease the amount when clicked (and rapidly do so when click-holding).
## sliders
sliders are used for controlling values in a quick manner by being dragged.
using the scroll wheel while holding Ctrl will change the slider's value by one in either direction.
right-clicking or Ctrl-clicking or a slider (Command-click on macOS) will turn it into a number input field for a short period of time, allowing you to input fine values.
